  • Often described as the Earth’s lungs, only in reverse, the tropical rainforests
  • What’s truly amazing, however, is that while the tropical rainforests cover just 2% of the Earth's land surface, they are home to two-thirds of all the living species on the planet. Additionally, "nearly half the medicinal compounds we use every day come from plants endemic to the tropical rainforest." If a cure for cancer or AIDS is to be found, it’ll almost certainly come from the tropical rainforests.
  • The Primary Source, writes that "tropical rainforests are the Earth’s oldest continuous ecosystems.

  • The largest rainforests are found in the Amazon Basin of South America, in Western African countries that skirt the equator, as well as South Pacific countries such as Indonesia and the Philippines.
  • Often described as the Earth’s lungs, only in reverse, the tropical rainforests, take in vast quantities of carbon dioxide (a poisonous gas which mammals exhale) and through the process of photosynthesis, converts it into clean, breathable air. In fact, the tropical rainforests are the single greatest terrestrial source of air that we breathe.

Project Amazonia: Threats - Agriculture and Cattle Ranching - 0 views

  •  
    Cattle For reasons similar to agriculture, ranching is not very adaptable to the land of the Amazon Rainforest. The grasses required to feed cattle, like the crops maintained in agriculture, are not resistant to the natural forces of the Amazon Basin and quickly deplete the nutrients of the surrounding soil. The nutrients that were once in the soil are removed from the ecosystem, shipped away as ground beef. Studies on land use have also suggested that the continuous movement of cattle on the unprotected land results in soil compacting, which increases the density of the soil material, resulting in decreased root penetration, water infiltration, and gas exchange.3 This means that larger flora, requiring a more extensive root system, are unable to grow under the compacted soil conditions, leaving the land for grass and woody shrub encroachment. The possible solutions to preventing nutrient loss are similar to those suggested for agricultural systems. Cattle ranching remains a very important industry in Brazil and is becoming even more vital to the Brazilian economy. The Brazilian commercial cattle herd is the largest in the world.4 Beef and milk are the two top livestock products in Brazil5 and exports of Brazilian beef grew to $1 billion (USD) in 2001. By 2003, Brazilian beef output is expected to reach 7.4 million tons, with exports of 925,000 tons. One problem in Brazilian beef exporting has been the existence of foot and mouth disease in some Brazilian states. This has caused the United States to be very stringent with Brazilian beef imports. However, the United States and Europe are still major importers of Brazilian beef.6 For every 1/4 lb hamburger consumed in the US from rainforest beef, about 55 square feet of rainforest was cleared. Although many fast food chains claim not to use rainforest beef, this claim is simply not valid. The USDA doesn't have an adequate system of labeling where beef is from. Thus beef grown in the rainforest can pass th

  •  
    How Ranching is Causing Deforestion It is the biggest cause of deforestation in the Amazon rainforest and 80% of the deforested areas in Brazil are used for pasture (Greenpeace). Ranches also use a large number of slave laborers. As the cattle grazes the area, they eat the grass and plants in the area and the soil becomes compacted and is no longer sustainable. The cattle ranchers then need to move to another area, destroying more of the rainforest and creating more unsustainable land causing a vicous cycle that keeps continuing. Rancher use the rainforest because it's a cheap way to raise cattle and then export it to other countries such as the United States. The demand for Brazilian beef has grown recently in the past few years due to control over diseases in Brazil (ex. foot-and-mouth disease), improvements and development of more roads into the forest, and how easy it is to gain title to land (which is to just clearing a part of the forest and placing some cattle there). There is so much ranching occurring in the rainforest due to how much easier it is to own cattle and acquire the land than it is to own crops.A Company Involved in Deforestation McDonald's is actively using the Brazil rainforest for their ranching purposes. It enables them to acquire wealth by burning down the rainforest and then paying ranchers to come in and raise cattle. The ranchers don't have a set minimum wage, as we do in the states, therefore they can be paid much less to work. It also doesn't cost much for them to acquire land. All they have to do is burn down a part of the rainforest and then place cattle on the land, then later they can export the beef back to the United States Ways to Prevent Ranching From Causing Deforestation Don't eat or support places such as McDonald's, KFC, or Burger King. Before you go out to eat, research the restaurant and see whether they have ranches in the rainforest. Donate to an organization or cause that is actively trying to stop ranching in the rain

Why are rainforests important? - 0 views

  • Rainforest in Honduras WHY ARE RAINFORESTS IMPORTANT? Flying over the heart of the Amazon is like flying over an ocean of green: an expanse of trees broken only by rivers. Even more amazing than their size is the role the Amazon and other rainforests around the world play in our everyday lives. While rainforests may seem like a distant concern, these ecosystems are critically important for our well-being.
  • Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet. Rainforests: help stabilize the world’s climate; provide a home to many plants and animals; maintain the water cycle protect against flood, drought, and erosion; are a source for medicines and foods; support tribal people; and are an interesting place to visit

Rainforest Concern - Why are rainforests important? - 0 views

  • They provide a habitat for plants and animals Tropical rainforests took between 60 and 100 million years to evolve and are believed to be the oldest and most complex land-based ecosystem on earth, containing over 30 million species of plants and animals. That's half of the Earth's wildlife and at least two-thirds of its plant species!

  • Without rainforests continually recycling huge quantities of water, feeding the rivers, lakes and irrigation systems, droughts would become more common, potentially leading to widespread famine and disease.
  • Did you know that we also depend on trees to cleanse our atmosphere? They absorb the carbon dioxide that we exhale, and provide the oxygen we need to breathe. When rainforest trees are burnt they release carbon dioxide, which pollutes the atmosphere and contributes to global warming. Deforestation is in fact considered the second major driver of climate change (more than the entire global transport sector), responsible for 18-25% of global annual carbon dioxide emissions.

How to Save Tropical Rainforests - Introduction - 0 views

  • Five Basic Steps to Saving Rainforests "TREES" is a concept originally devised for an elementary school audience but serves well as set of principles for saving rainforests and, on a broader scale, ecosystems around the world. Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment. Establish parks to protect rainforests and wildlife. Support companies that operate in ways that minimize damage to the environment.

Medicinal Treasures of the Rainforest: Discover the healing resources of the Amazon - 1 views

  • A look at the botanical treasures, both known and undiscovered, that exist within tropical rainforests.
  • The abundant botanical resources of tropical forests have already provided tangible medical advances; yet only 1 percent of the known plant and animal species have been thoroughly examined for their medicinal potentials.
  • 20 or 25 percent of the world's plant species will be extinct by the year 2000.
  • ...9 more annotations...
  • Approximately 7,000 medical compounds prescribed by Western doctors are derived from plants
  • These drugs had an estimated retail value of US$43 billion in 1985
  • For maladies ranging from nagging headaches to lethal contagions such as malaria, rainforest medicines have provided modern society with a variety of cures and pain relievers.
  • • Quinine, an aid in the cure of malaria, is an alkaloid extracted from the bark of the cinchona tree found in Latin America and Africa. • From the deadly poisonous bark of various curare lianas, used by generations of indigenous peoples in Latin America, has been isolated the alkaloid d-turbocuarine, which is used to treat such diseases as multiple sclerosis, Parkinson's disease and other muscular disorders. It also permits tonsillectomies, eye, abdominal and other kinds of surgery due to its anesthetic qualities. • From Africa, Madagascar's rosy periwinkle provides two important anti-tumor agents. One provides for a 99 percent chance of remission in cases of lymphocytic leukemia. The other offers a life in remission to 58 percent of Hodgkin's Disease sufferers. In 1960, only 19 percent had a chance for survival. Commercial sales of drugs derived from this one plant are about US$160 million a year. • Without wild yams from Mexico and Guatemala, society would be without diosgenin and cortisone, the active ingredients in birth control pills. Until recently this plant provided the world with its entire supply of diosgenin.
  • Finally, rainforest plants provide aids for research.
  • testing agents for potentially harmful food and drug products
  • Tropical forests offer hope for safer contraceptives for both women and men. The exponential growth of world population clearly demonstrates the need for more reliable and effectiv
  • e birth control methods. Worldwide, approximately 4,000 plant species have been shown to offer contraceptive possibilities.
  • The chemical components of plants that medicine men use in healing rites could conceivably be building blocks for new drugs or even cures for such scourges as cancer or AIDS.

How cattle ranches are chewing up the Amazon rainforest | Greenpeace UK - 1 views

  • Cattle ranching is now the biggest cause of deforestation in the Amazon, and nearly 80 per cent of deforested areas in Brazil are now used for pasture. The cattle industry has ballooned since the 1970s, giving Brazil the largest commercial cattle herd in the world. Since 2003, the country has also topped the world's beef export charts and the government plans to double its share of the market by 2018.
  • Deforestation is largely responsible for making Brazil the fourth largest greenhouse gas emitter, and the cattle industry also contributes a significant quantity of emissions in the form of bovine methane emissions (or cow farts if you want to be less tactful).
