Preserve the rainforest
Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth's tropical rain forests.
40 to 75% of all species on the world's habitats are indigenous to the rainforests.Rainforests.net It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the "jewels of the Earth", and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there.Rainforests are also responsible for 28% of the world's oxygen turn over, often misunderstood as oxygen production,[1] processing it through photosynthesis from carbon dioxide and storing it as carbon through biosequestration.
The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs, and small trees called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest.
[edit] Tropical
Many of the world's rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone. Tropical rainforests are rainforests in the tropics, found near the Equator (between the Tropic of Cancer and Tropic of Capricorn) and present in Southeast Asia (Myanmar to Philippines, Indonesia, Papua New Guinea, and northeastern Australia), Sri Lanka, Sub-Saharan Africa from Cameroon to the Congo (Congo Rainforest), South America (e.g. the Amazon Rainforest), Central America (e.g. Bosawás, southern Yucatán Peninsula-El Peten-Belize-Calakmul), and on many of the Pacific Islands (such as Hawaiʻi). Tropical rainforests have been called the "Earth's lungs," although it is now known that rainforests contribute little net oxygen additions to the atmosphere through photosynthesis.Columbia UniSpringerlink
[edit] Temperate
Temperate rainforests are rainforests in temperate regions. They can be found in North America (in the Pacific Northwest, the British Columbia Coast, and in the inland rainforest of the Rocky Mountain Trench east of Prince George), in Europe (parts of the British Isles such as the coastal areas of Ireland, Scotland, southern Norway, parts of the western Balkans along the Adriatic coast, as well as in the North West of Spain and coastal areas of the eastern Black Sea, including Georgia and coastal Turkey), in East Asia (in southern China, Taiwan, much of Japan and Korea, and on Sakhalin Island and the adjacent Russian Far East coast), in South America (southern Chile) and also Australia and New Zealand
[edit] Layers
A tropical rainforest is typically divided into four main layers, each with different plants and animals adapted for life in that particular area: the emergent, canopy, understory, and forest floor layers.
[edit] Emergent layer
The emergent layer contains a small number of very large trees called emergents, which grow above the general canopy, reaching heights of 45–55 m, although on occasion a few species will grow to 70–80 m tall. They need to be able to withstand the hot temperatures and strong winds in some areas. Eagles, butterflies, bats, and certain monkeys inhabit this layer.
[edit] Canopy layer
The canopy layer contains the majority of the largest trees, typically 30–45 m tall. The densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by some estimates, is home to 50 percent of all plant species, suggesting that perhaps half of all life on Earth could be found there. Epiphytic plants attach to trunks and branches, and obtain water and minerals from rain and debris that collects on the supporting plants. The fauna is similar to that found in the emergent layer, but more diverse. A quarter of all insect species are believed to exist in the rainforest canopy. Scientists have long suspected the richness of the canopy as a habitat, but have only recently developed practical methods of exploring it. As long ago as 1917, naturalist William Beebe declared that "another continent of life remains to be discovered, not upon the Earth, but one to two hundred feet above it, extending over thousands of square miles." True exploration of this habitat only began in the 1980s, when scientists developed methods to reach the canopy, such as firing ropes into the trees using crossbows. Exploration of the canopy is still in its infancy, but other methods include the use of balloons and airships to float above the highest branches and the building of cranes and walkways planted on the forest floor. The science of accessing tropical forest canopy using airships, or similar aerial platforms, is called dendronautics.
[edit] Understory layer
The understory layer lies between the canopy and the forest floor. The understory (or understorey) is home to a number of birds, snakes, and lizards, as well as predators such as jaguars, boa constrictors, and leopards. The leaves are much larger at this level. Insect life is also abundant. Many seedlings that will grow to the canopy level are present in the understory. Only about 5 percent of the sunlight shining on the rainforest reaches the understory. This layer can also be called a shrub layer, although the shrub layer may also be considered a separate layer.
[edit] Forest floor
The forest floor, the bottom-most layer, receives only 2 percent of sunlight. Only plants adapted to low light can grow in this region. Away from riverbanks, swamps, and clearings where dense undergrowth is found, the forest floor is relatively clear of vegetation because of the low sunlight penetration. It also contains decaying plant and animal matter, which disappears quickly due to the warm, humid conditions promoting rapid decay. Many forms of fungi grow here which help decay the animal and plant waste.
[edit] Flora and fauna
More than half of the world's species of plants and animals are found in the rainforest. Rainforests support a very broad array of fauna including mammals, reptiles, birds, and invertebrates. Mammals may include primates, felids, and other families. Reptiles include snakes, turtles, chameleons, and other families while birds include such families as vangidae and Cuculidae. Dozens of families of invertebrates are found in rainforests. Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plant and animal life. These species are rapidly disappearing due to deforestation, habitat loss, and biochemical releases into the atmosphere.
[edit] Soils
Despite the growth of vegetation in a tropical rainforest, soil quality is often quite poor. Rapid bacterial decay prevents the accumulation of humus. The concentration of iron and aluminium oxides by the laterization process gives the oxisols a bright red color and sometimes produces minable deposits such as bauxite. Most trees have roots near the surface as there are not many nutrients below the ground; most of the trees minerals come from the top layer of decomposing leaves (mainly) and animals. On younger substrates, especially of volcanic origin, tropical soils may be quite fertile. If the trees are cleared, the rain can get at the exposed soil, washing it away. Eventually streams will form, then rivers. Flooding becomes possible.
[edit] The Wealth of the Rainforests
- The Amazon Rainforest covers over a billion acres, encompassing areas in Brazil, Venezuela, Colombia and the Eastern Andean region of Ecuador and Peru. If Amazonia were a country, it would be the ninth largest in the world.
- The Amazon Rainforest has been described as the "Lungs of our Planet" because it provides the essential environmental world service of continuously recycling carbon dioxide into oxygen. More than 20 percent of the world oxygen is produced in the Amazon Rainforest.
- More than half of the world's estimated 10 million species of plants, animals and insects live in the tropical rainforests. One-fifth of the world's fresh water is in the Amazon Basin.
- One hectare (2.47 acres) may contain over 750 types of trees and 1500 species of higher plants.
- At least 80% of the developed world's diet originated in the tropical rainforest. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.
- At least 3000 fruits are found in the rainforests; of these only 200 are now in use in the Western World. The Indians of the rainforest use over 2,000.
- Rainforest plants are rich in secondary metabolites, particularly alkaloids. Biochemists believe alkaloids protect plants from disease and insect attacks. Many alkaloids from higher plants have proven to be of medicinal value and benefit.
- Currently, 121 prescription drugs currently sold worldwide come from plant-derived sources. And while 25% of Western pharmaceuticals are derived from rainforest ingredients, less than 1% of these tropical trees and plants have been tested by scientists.
- The U.S. National Cancer Institute has identified 3000 plants that are active against cancer cells. 70% of these plants are found in the rainforest. Twenty-five percent of the active ingredients in today's cancer-fighting drugs come from organisms found only in the rainforest.
- Vincristine, extracted from the rainforest plant, periwinkle, is one of the world's most powerful anticancer drugs. It has dramatically increased the survival rate for acute childhood leukemia since its discovery.
- In 1983, there were no U.S. pharmaceutical manufacturers involved in research programs to discover new drugs or cures from plants. Today, over 100 pharmaceutical companies and several branches of the US government, including giants like Merck and The National Cancer Institute, are engaged in plant research projects for possible drugs and cures for viruses, infections, cancer, and even AIDS.
[edit] Rainforest Action
- Experts agree that by leaving the rainforests intact and harvesting it's many nuts, fruits, oil-producing plants, and medicinal plants, the rainforest has more economic value than if they were cut down to make grazing land for cattle or for timber.
- The latest statistics show that rainforest land converted to cattle operations yields the land owner $60 per acre and if timber is harvested, the land is worth $400 per acre. However, if these renewable and sustainable resources are harvested, the land will yield the land owner $2,400 per acre.
- If managed properly, the rainforest can provide the world's need for these natural resources on a perpetual basis.
- Promoting the use of these sustainable and renewable sources could stop the destruction of the rainforests. By creating a new source of income harvesting the medicinal plants, fruits nuts, oil and other sustainable resources, the rainforests is be more valuable alive than cut and burned.
- Sufficient demand of sustainable and ecologically harvested rainforest products is necessary for preservation efforts to succeed. Purchasing sustainable rainforest products can effect positive change by creating a market for these products while supporting the native people's economy and provides the economic solution and alternative to cutting the forest just for the value of its timber.
[edit] Effect on global climate
A natural rainforest emits and absorbs vast quantities of carbon dioxide. On a global scale, long-term fluxes are approximately in balance, so that an undisturbed rainforest would have a small net impact on atmospheric carbon dioxide levels, though they may have other climatic effects (on cloud formation, for example, by recycling water vapor). No rainforest today can be considered to be undisturbed. Human induced deforestation plays a significant role in causing rainforests to release carbon dioxide, as do natural processes such as drought that result in tree death. Some climate models run with interactive vegetation and predict a large loss of Amazonian rainforest around 2050 due to drought, leading to forest dieback and the subsequent feedback of releasing more carbon dioxide.
[edit] Human uses
Tropical rainforests provide timber as well as animal products such as meat and hides. Rainforests also have value as tourism destinations and for the ecosystem services provided. Many foods originally came from tropical forests, and are still mostly grown on plantations in regions that were formerly primary forest. Also, plant derived medicines are commonly used for fever, fungal infections, burns, gastrointestinal problems, pain, respiratory problems, and wound treatment.
[edit] Native peoples
On January 18, 2007, FUNAI reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition, Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted tribes. The province of Irian Jaya or West Papua in the island of New Guinea is home to an estimated 44 uncontacted tribal groups.
Central African rainforest is home of the Mbuti pygmies, one of the hunter-gatherer peoples living in equatorial rainforests characterised by their short height (below one and a half metres, or 59 inches, on average). They were the subject of a study by Colin Turnbull, The Forest People, in 1962.[[2]] Pygmies who live in Southeast Asia are, amongst others, referred to as “Negritos.”
[edit] Deforestation[[3]]
Tropical and temperate rainforests have been subjected to heavy logging and agricultural clearance throughout the 20th century and the area covered by rainforests around the world is shrinking.[[4]] Biologists have estimated that large numbers of species are being driven to extinction (possibly more than 50,000 a year; at that rate, says E. O. Wilson of Harvard University, a quarter or more of all species on Earth could be exterminated within 50 years) due to the removal of habitat with destruction of the rainforests.
Another factor causing the loss of rainforest is expanding urban areas. Littoral rainforest growing along coastal areas of eastern Australia is now rare due to ribbon development to accommodate the demand for seachange lifestyles.
The forests are being destroyed at a rapid pace. Almost 90% of West Africa's rainforest has been destroyed.[[5]] Since the arrival of humans 2000 years ago, Madagascar has lost two thirds of its original rainforest. At present rates, tropical rainforests in Indonesia would be logged out in 10 years and Papua New Guinea in 13 to 16 years.[[6]]
Several countries,[[7]] notably Brazil, have declared their deforestation a national emergency.[[8]] Amazon deforestation jumped by 69% in 2008 compared to 2007's twelve months, according to official government data.[[9]] Deforestation could wipe out or severely damage nearly 60% of the Amazon Rainforest by 2030, says a new report from WWF.[[10]]
However, a January 30, 2009 New York Times article stated, "By one estimate, for every acre of rain forest cut down each year, more than 50 acres of new forest are growing in the tropics..." The new forest includes secondary forest on former farmland and so-called degraded forest.[[11]]
From a new recent report in September 2009, new opportunities are beginning to discover they could save the rainforest. In Brazil, Environment Minister Carlos Minc announced proudly that the rate of deforestation of the Amazon fell by 46 percent last year. That means the lowest logging level since the country began to keep annual statistics 21 years ago. But not only Brazil has reduced deforestation as a whole also slowed the loss of forest down. The annual decline is now over two thousand. Deforestation decreases in a country as it becomes richer and more industrialized. Therefore, there are exceptions in a group of countries where deforestation has become so profitable that it is an important part in the growth of prosperity. New goal is to stop felling the forest, but also in managing the forest long-term, which occurs on a larger scale. More police officers guarding the rainforest, and stifle the illegal logging.
The world's rainforests are currently disappearing at a rate of 6000 acres every hour (this is about 4000 football fields per hour). When these forests are cut down, the plants and animals that live in the forests are destroyed, and some species are at risk of being made extinct. Further, as the large-scale harvesting of lumber from the rain forests continues, the balance of the earth's eco-system is disrupted. We need the rain forests to produce oxygen and clean the atmosphere to help us breathe. We also know that the earth's climate can be affected, as well as the water cycle. Rainforests also provide us with many valuable medicinal plants, and may be a source of a cure from some deadly diseases.
Forests can be managed effectively without endangering rare species of plants and animals and without risking global environmental damage. Companies that harvest timber should not be allowed to "clear cut" large areas of forest and should be required to plant new trees after they cut old trees down. Governments should create large parks and reserves where hunting and logging are not allowed. As a world community, we must be careful not to destroy the resources that people will need in the future.
Many animals from the rainforests are brought to our country illegally. Parrots and iguanas, for example, are often imported illegally. We should not buy these animals, since that encourages other people to bring in more animals.
Most of the products that we use in our country come from rainforests, such as rubber, coffee and rain forest lumber. Rainforests are cut down to harvest the timber and also to make room for farms to grow coffee and spices. Each of us needs to be thoughtful about the way we consume these products, and support companies and programs that make a commitment to safe environmental practices. Recycle and re-use whenever possible, and help keep the earth green and healthy.
[edit] The Negative Effects of Deforestation
- Prevention of deforestation is important for the stability of the environment and all living things, as the following negative effects are already causing serious irreversible damage throughout the world:
A) Irreversible Environment Changes:
- Sadly, some parts of the world have experienced detrimental consequences as a result of deforestation. For instance, they no longer are able to enjoy thriving biodiversity and must find ways to cope with continuous environmental changes. The majority of countries that have undergone massive deforestation are dealing with unforeseen transformation in climate and geography because the ability of forests to sustain a balance in climate changes is hindered. The outcome - natural habitats and biodevirsity shrinks by the minute.
B) Decline in Wood:
- Deforestation causes a dramatic decline in thw wood that satisfies industrial, fuel, and other human needs.
C) Living Conditions:
- The overall quality of life declines when deforestation takes place - especially in regions where degraded land is found.
D) Water Conditions:
- Deforesattion plays a role in the amount of water found in the soil, as well as the level of moisture in the atmospher.
E) Medicinal Loss:
- Researches have uncovered the sources to a wealth of new drugs within forest biotopes located all over the world. With deforestation, the genetic variations (like to resistance) that scientists would like to preserve are geatly threatened.
F) Precipitation:
- The loss of vital trees and plants affect the water cycle in many different ways, as the absence of litter, stems, and truks of tress all play an important role. With less forest covering the land, the ability to 'intercept' retain, and transport precipitation is affected. When precipitation is not trapped, surface water transport occurs at a faster rate. Possible outcomes include flash floods.
G) Increased pollution:
- You've heard of trees and the role they play in regards to our air. Trees serve as significant managers of organic carbon and forest possess the capacity to remove harmful pollutants from the air. Without trees working in our favor, increased pollution is allowed to take place.
H) Shrinking Beauty:
- Forests are green visions of natural beauty that are valued for their cultural resource. Simply put - they are 'nice' to look at and fun to explore during family vacations or adventure hikes. In some parts of the world, they provide great tourist attractions.
I) Financial Impact:
- Although the wood found in forests is used to supply people with timber, wood fuel (for heating and cooking), and wood pulp (for paper) - the long-term financial impact far outweighs the short-term gain. The use of forests for the creation of wood products or the conversion of forest to agriculture has actually developed financial woes, as both West Africa and Southeast Asia have in timber harvests. Also - illegal logging comes with a price each year that can cost national economies billions of dollars to compensate.
[edit] How to Prevent Deforestation
You don't have to live in the middle of the rainforest to do your part in preventing deforestation. Below are a few suggestions to consider when you are interested in preserving the amount of forests located in the rest of the world, as well as right in your own backyard:
A.) Use Recycled Items:
- Today, a consumer can purchase a variety of recycled items, including notebook paper, books, toilet paper, and shopping bags. When people use recyclesd products and make a concious effort not to waste, the demand for new raw material to replace these items can decrease.
B.) Tree Care:
- When cutting down trees - single out full-grown specimens and spare younger varieties. In the event that you must remove a tree for a legitimate reason (for safety issues or power line interference), make sure that for every tree lost - another is planted in its place.
C.) Farming Practies:
- Those who plant crops at a farm can participate in putting a dent in deforestation by rotating crops. It is suggested to replace the habit of using different portions of land each year with using the same portion of land to plant different crops. This practice has proven effective in maintaining soil fertility. Farmers may also embrace many other options, such as high-yield hybrid crops and hydroponics, which relies on a method of growing plants using meneral nutreint solutions instead of soil.
D.) Cut Bak on Palm Oil:
- In Malaysia and Indonesia, an increasing amount of trees are cut down in order to generate the palm oil used in the production of some breads, chocolates, and shampoos. As a result, the native orangutans are losing their habitat. You can spread awareness and limit your consumption of products containing this type of oil.
E.) Coals:
- As the chill of winter takes over the autumn season, try using coals instead of firewood in your fireplace. While it only takes a couple of hours to consume a few logs here and there, keep in mind that it takes years for one tree to fully grow.
F.) Reforestation:
- Take a page from the People's Republic of China, where the government that in the past set a requirement that every able-bodied citizen between that the ages of 11 and 60 is responsible for planting three to five trees per year or complete an equal amount of work in other areas of forestry. Since 1982, the government claims that at least one billion trees have been planted in China as a result of the program.
G.) Become an Advocate:
- Become an advocate of reforestation. Learn how you can spread the word. For instance, a middle school in Washington took to the streets asking people for just one penny. They explained that the money would go towards purchasing acres of Amazonian rainforest. If successful, this move ensures that no deforestation can take place on the bought land. The effort was two fold - spreading information and collecting money for a good cause.
H.) Arbor Day Foundation's Rain Forest Rescue:
- Support programs, such as this Arbor Day Foundation gem, which assists in the prevention of deforestation. Donated money is used to purchase and preserve rainforest space before lumber companies can get a hold of the land. As a result, the Arbor Day Foundation is able to protect the land from deforestation.
I.) Support Conservation Organization:
- Lend your support through donations of yout time, money, or actions to organizations that run programs concentrating on the preservation of forests habitats, such as Greenpeace, World Wide Fund for Nature, Community Forestry International, and Conservation International.
[edit] THE IMPORTANCE OF THE RAINFOREST [[12]]
The beauty, majesty, and timelessness of a primary rainforest are indescribable. It is impossible to capture on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest.
Rainforests[[13]] have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever.
The scale of human pressures on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen- at a cost to our ecosystems. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; unfortunately, it is still the tropical forests of the world that supply the bulk of the world's demand for wood.
In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in smoke. In fewer than fifty years, more than half of the world's tropical rainforests have fallen victim to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years.
Massive deforestation brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming.
But who is really to blame? Consider what we industrialized Americans have done to our own homeland. We converted 90 percent of North America's virgin forests into firewood, shingles, furniture, railroad ties, and paper. Other industrialized countries have done no better. Malaysia, Indonesia, Brazil, and other tropical countries with rainforests are often branded as "environmental villains" of the world, mainly because of their reported levels of destruction of their rainforests. But despite the levels of deforestation, up to 60 percent of their territory is still covered by natural tropical forests. In fact, today, much of the pressures on their remaining rainforests comes from servicing the needs and markets for wood products in industrialized countries that have already depleted their own natural resources. Industrial countries would not be buying rainforest hardwoods and timber had we not cut down our own trees long ago, nor would poachers in the Amazon jungle be slaughtering jaguar, ocelot, caiman, and otter if we did not provide lucrative markets for their skins in Berlin, Paris, and Tokyo.
[edit] The Disappearing Rainforests
- We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.
- One and one-half acres of rainforest are lost every second with tragic consequences for both developing and industrial countries.
- Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners.
- Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation.
- Experts estimates that we are losing 137 plant, animal and insect species every single day due to rainforest deforestation. That equates to 50,000 species a year. As the rainforest species disappear, so do many possible cures for life-threatening diseases. Currently, 121 prescription drugs sold worldwide come from plant-derived sources. While 25% of Western pharmaceuticals are derived from rainforest ingredients, less that 1% of these tropical trees and plants have been tested by scientists.
- Most rainforests are cleared by chainsaws, bulldozers and fires for its timber value and then are followed by farming and ranching operations, even by world giants like Mitsubishi Corporation, Georgia Pacific, Texaco and Unocal.
- There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000.
- In Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 1900's. With them have gone centuries of accumulated knowledge of the medicinal value of rainforest species. As their homelands continue to be destroyed by deforestation, rainforest peoples are also disappearing.
- Most medicine men and shamans remaining in the Rainforests today are 70 years old or more. Each time a rainforest medicine man dies, it is as if a library has burned down.
- When a medicine man dies without passing his arts on to the next generation, the tribe and the world loses thousands of years of irreplaceable knowledge about medicinal plants.
[edit] THE BIODIVERSITY OF THE RAINFOREST
Why should the loss of tropical forests be of any concern to us in light of our own poor management of natural resources? The loss of tropical rainforests has a profound and devastating impact on the world because rainforests are so biologically diverse, more so than other ecosystems (e.g., temperate forests) on Earth.
Consider these facts:
- A single pond in Brazil can sustain a greater variety of fish than is found in all of Europe's rivers.
- A 25-acre plot of rainforest in Borneo may contain more than 700 species of trees - a number equal to the total tree diversity of North America.
- A single rainforest reserve in Peru is home to more species of birds than are found in the entire United States.
- One single tree in Peru was found to harbor forty-three different species of ants - a total that approximates the entire number of ant species in the British Isles.
- The number of species of fish in the Amazon exceeds the number found in the entire Atlantic Ocean.
The biodiversity of the tropical rainforest is so immense that less than 1 percent of its millions of species have been studied by scientists for their active constituents and their possible uses. When an acre of topical rainforest is lost, the impact on the number of plant and animal species lost and their possible uses is staggering. Scientists estimate that we are losing more than 137 species of plants and animals every single day because of rainforest deforestation.
Surprisingly, scientists have a better understanding of how many stars there are in the galaxy than they have of how many species there are on Earth. Estimates vary from 2 million to 100 million species, with a best estimate of somewhere near 10 million; only 1.4 million of these species have actually been named. Today, rainforests occupy only 2 percent of the entire Earth's surface and 6 percent of the world's land surface, yet these remaining lush rainforests support over half of our planet's wild plants and trees and one-half of the world's wildlife. Hundreds and thousands of these rainforest species are being extinguished before they have even been identified, much less catalogued and studied. The magnitude of this loss to the world was most poignantly described by Harvard's Pulitzer Prize-winning biologist Edward O. Wilson over a decade ago:
"The worst thing that can happen during the 1980s is not energy depletion, economic collapses, limited nuclear war, or conquest by a totalitarian government. As terrible as these catastrophes would be for us, they can be repaired within a few generations. The one process ongoing in the 1980s that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly that our descendants are least likely to forgive us for."
Yet still the destruction continues. If deforestation continues at current rates, scientists estimate nearly 80 to 90 percent of tropical rainforest ecosystems will be destroyed by the year 2020. This destruction is the main force driving a species extinction rate unmatched in 65 million years.
[edit] UNLOCKING THE SECRETS OF THE RAINFOREST
After the Amerindians discovered America, about twenty millennia before Columbus, all their clothing, food, medicine, and shelter were derived from the forests. Those millennia gave the Indians time to discover and learn empirically the virtues and vices of the thousands of edible and medicinal species in the rainforest. More than 80 percent of the developed world's diet originated in the rainforest and from this empirical indigenous knowledge of the wealth of edible fruits, vegetables, and nuts. Of the estimated 3,000 edible fruits found in the rainforest, only 200 are cultivated for use today, despite the fact that the Indians used more than 1,500. Many secrets and untold treasures about the medicinal plants used by shamans, healers, and the indigenous people of the rainforest tribes await discovery. Long regarded as hocus-pocus by science, the empirical plant knowledge of the indigenous peoples is now thought by many to be the Amazon's new gold. Their use of the plants provides the bioprospector with the clues necessary to target specific species to research in the race for time before the species are lost to deforestation. More often, the race is defined as being the first pharmaceutical company to patent a new drug utilizing a newly discovered rainforest phytochemical-and, of course, to garner the profits.
[edit] LOSING THE KNOWLEDGE
The destruction of the rainforest has followed the pattern of seeing natural land and natural world peoples as resources to be used, and seeing wilderness as idle, empty, and unproductive. Destruction of our rainforests is not only causing the extinction of plant and animal species, it is also wiping out indigenous peoples who live in the rainforest. Obviously, rainforests are not idle land, nor are they uninhabited. Indigenous peoples have developed technologies and resource use systems that have allowed them to live on the land, farming, hunting, and gathering in a complex sustainable relationship with the forest. But when rainforests die, so do the indigenous peoples.
In 1500 there were an estimated 6 million to 9 million indigenous people inhabiting the rainforests in Brazil. When Western and European cultures were drawn to Brazil's Amazon in the hopes of finding riches beyond comprehension and artifacts from civilizations that have long since expired with the passage of time, they left behind decimated cultures in their ravenous wake. By 1900 there were only 1 million indigenous people left in Brazil's Amazon. Although the fabled Fountain of Youth was never discovered, many treasures in gold and gems were spirited away by the more successful invaders of the day, and the indigenous inhabitants of the rainforest bore the brunt of these marauding explorers and conquistadors.
Today there are fewer than 250,000 indigenous people of Brazil surviving this catastrophe, and still the destruction continues. These surviving indigenous people still demonstrate the remarkable diversity of the rainforest because they comprise 215 ethnic groups with 170 different languages. Nationwide, they live in 526 territories, which together compose an area of 190 million acres . . . twice the size of California. About 188 million acres of this land is inside the Brazilian Amazon, in the states of Acre, Amapa, Amazonas, Maranhao, Mato Grosso, Para, Rondonia, Roraima, and Tocantins. There may also be 50 or more indigenous groups still living in the depths of the rainforest that have never had contact with the outside world.
Throughout the rainforest, forest-dwelling peoples whose age-old traditions allow them to live in and off the forest without destroying it are losing out to cattle ranching, logging, hydroelectric projects, large-scale farms, mining, and colonization schemes. About half of the original Amazonian tribes have already been completely destroyed. The greatest threat to Brazil's remaining tribal people, most of whom live in the Amazon rainforest, is the invasion of their territory by ranchers, miners, and land speculators and the conflicts that follow. Thousands of peasants, rubber tappers, and indigenous tribes have been killed in Amazonia in the past decade in violent conflicts over forest resources and land.
As their homelands continue to be invaded and destroyed, rainforest people and their cultures are disappearing. When these indigenous peoples are lost forever, gone too will be their empirical knowledge representing centuries of accumulated knowledge of the medicinal value of plant and animal species in the rainforest. Very few tribes have been subjected to a complete ethnobotanical analysis of their plant knowledge, and most medicine men and shamans remaining in the rainforests today are seventy years old or more. When a medicine man dies without passing his arts on to the next generation, the tribe and the world lose thousands of years of irreplaceable knowledge about medicinal plants. Each time a rainforest medicine man dies, it is as if a library has burned down.
[edit] THE SOLUTION: PROFITS WITHOUT PLUNDER
The problem and the solution of the destruction of the rainforest are both economic. Governments need money to service their debts, squatters and settlers need money to feed their families, and companies need to make profits. The simple fact is that the rainforest is being destroyed for the income and profits it yields, however fleeting. Money still makes the world go around . . . even in South America and even in the rainforest. But this also means that if landowners, governments, and those living in the rainforest today were given a viable economic reason not to destroy the rainforest, it could and would be saved. And this viable economic alternative does exist, and it is working today. Many organizations have demonstrated that if the medicinal plants, fruits, nuts, oils, and other resources like rubber, chocolate, and chicle (used to make chewing gums) are harvested sustainably, rainforest land has much more economic value today and more long-term income and profits for the future than if just timber is harvested or burned down for cattle or farming operations. In fact, the latest statistics prove that rainforest land converted to cattle operations yields the landowner $60 per acre; if timber is harvested, the land is worth $400 per acre. However, if medicinal plants, fruits, nuts, rubber, chocolate, and other renewable and sustainable resources are harvested, the land will yield the landowner $2,400 per acre. This value provides an income not only today, but year after year - for generations. These sustainable resources - not the trees - are the true wealth of the rainforest.
This is no longer a theory. It is a fact, and it is being implemented today. Just as important, to wild-harvest the wealth of sustainable rainforest resources effectively, local people and indigenous tribes must be employed. Today entire communities and tribes earn five to ten times more money in wild-harvesting medicinal plants, fruits, nuts, and oils than they can earn by chopping down the forest for subsistence crops. This much-needed income source creates the awareness and economic incentive for this population in the rainforest to protect and preserve the forests for long-term profits for themselves and their children and is an important solution in saving the rainforest from destruction.
When the timber is harvested for short-term gain and profits, the medicinal plants, nuts, oils, and other important sustainable resources that thrive in this delicate ecosystem are destroyed. The real solution to saving the rainforest is to make its inhabitants see the forest and the trees by creating a consumer demand and consumer markets for these sustainable rainforest products . . . markets that are larger and louder than today's tropical timber market . . . markets that will put as much money in their pockets and government coffers as the timber companies do . . . markets that will give them the economic incentive to protect their sustainable resources for long-term profits, rather than short-term gain.
This is the only solution that makes a real impact, and it can make a real difference. Each and every person in the United States can take a part in this solution by helping to create this consumer market and demand for sustainable rainforest products. By purchasing renewable and sustainable rainforest products and resources and demanding sustainable harvesting of these resources using local communities and indigenous tribes of the rainforests, we all can be part of the solution, and the rainforests of the world and their people can be saved.
