  • 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 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.

  • For biologists, tropical rainforests are some of the richest, most exciting areas on earth! They are home to gigantic trees, colourful birds, millions of brightly hued insects, and a variety of fascinating mammals. There are 3 main regions of tropical rainforest: in Central and South America, in West and Central Africa, and in Southeast Asia.
  • ropical rainforests have more kinds of trees than any other forests in the world. The richest in plant species are Amazon forests, but in general all tropical forests have an incredible variety of trees

  • 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.

  • When the trees are cut down it takes away the habitat of the plants and animals. It also reduces the space for the indigenous people who have lived there for thousands of years.
  • This way of life has died out with contact from incomers.
  • Some native groups suffered greatly from diseases which they had no resistance to.
  • ...3 more annotations...
  • Deforestation has led to the loss of thousands of species of insects, animals and plants. It means that important chemicals that could be used for medical purposes have not been found and will be lost.
  • Without the branches and leaves to break its fall, heavy tropical storms can quickly wash the soil from even an gentle slope.
  • The climate of the area becomes drier with the loss of the vegetation which acts as a "sponge" to hold on to the moisture. Having less cloud cover means the increase in temperatures. Both the burning of the trees and their reduced number increases the concentration of carbon dioxide. The extra carbon dioxide is believed to contribute to global warming, which in turn is blamed for the rise in sea level.

  • Most alarming, says the report, is that many of these changes have accelerated in the past decade, despite the plethora of international conventions signed since the initial Rio Summit in 1992.
  • Climate-warming carbon emissions have increased 40% in the past 20 years, but two-thirds of that rise occurred in the past decade.
  • Wealthy countries have seen some improvement, with the Living Planet biodiversity index, rising 7% since 1970, as nature reserves and protections were introduced. But the biodiversity index has dropped by 60% in developing countries, where people depend more on nature.

  • 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.

  • 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.

  • Threats Intensive commercial logging has destroyed more than 90% of the native forests of this ecoregion. The immense size of the mighty redwood trees, and the beauty of their wood, has made them a target for loggers for more than a century. Even logging in surrounding watersheds can have severe repercussions for redwood groves, since it can cause severe flooding, fires, and sedimentation. The spread of urban areas between Monterey and San Francisco, along with the introduction of exotic plants into these ancient forests, exacerbate the problems. Cruise ships can lead to pollution, as well as disturbing whales and other marine mammals. Other threats include pollution from pulp mills and mines. Introduced beavers are also creating problems for native wildlife. Their damming of small streams is making it difficult for Coho salmon to travel upstream and spawn. Similarly, introduced rats, squirrels, and raccoons have reduced the size of seabird colonies as they prey on eggs and young birds.

      The carbon storage service provided by the world's forests is vital for climate stabilization. The amount of carbon stored in different forests varies: Tropical forests store the most carbon, with current estimates suggesting the above-ground biomass stores of these  forests is 247 Gt C (Chavez et al., 2008; Lewis et al., 2009; Mahli  et al., 2006; UNEP, 2010), which is five times more than the current global carbon emissions of 47 Gt per year (UNEP, 2010).
