There are many reasons why rainforests are important which can be put under the following headings: Biodiversity Rainforests contain about half of the existing plant and animal species in the world.
The remaining African rainforests contain more animals and plant species than are found anywhere else on the continent. In just one year in19 new species of lemur were officially recorded Te importance of rainforests Madagascar.
Medicines Hundreds of rainforest plants are used in modern medicines. Curare, a poison used by Amazonian Indians on arrow tips can be used as a muscle relaxant if given in small doses.
Many food sources are still being discovered in rainforests. The fruit has twice the food value of banana and more protein and carbohydrate than maize. The forests and soil also lock away carbon, an important function, especially in this age when humans are causing so much carbon dioxide to be released into the atmosphere through, for example, transport and fossil fuel power stations.
Where trees are cut down in large numbers, this natural protection is removed, soil erosion increases and minerals are washed away. Trees also help to control the amount of water that is held in the soil.
In areas around the world where forests have been felled, the rainfall patterns have changed. In some places, the rains have almost stopped falling, and in others, flooding has been caused. People In South East Asia and the Pacific Islands, people have lived in the forests for about 40, years, but the earliest signs of human settlement in African forests are no more than 3, years old.
There are about 1, indigenous tribes in the rainforests of the world. Rainforest tribes have managed to develop ways of life which allow them to use the forest without destroying it. Whilst other civilisations have grown further and further from the natural world, these tribes have had to grow close to nature in order to survive.
European settlers have caused many of these tribes to be wiped out due to their lack of immunity to Western diseases. They now face a new threat as big logging, plantation, oil and hyrdoelectric companies try to force them off their traditional lands, often using violence.
Millions of indigenous people depend on rainforests for their survival and over a billion make their livelihoods from its products.
See our fact sheet Rainforest Tribes below for more information.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.
What are Rainforests? Rainforests are the forests characterized with tall trees, relatively warm climates and a great degree of rain on an annual basis. Most rainforests have an annual rainfall in the ranges of to centimeters (98 to inches).
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. Importance of rainforests can be derived from the items that they supply.
Some of these are listed below: Natural medicines; Oxygen production; Sugar; Spices such as coconut, vanilla, turmeric, ginger etc.

Rainforests are the forests characterized with tall trees, relatively warm climates and a great degree of rain on an annual basis. Most rainforests have an annual rainfall in the ranges of to centimeters (98 to inches). What is a Rainforest? Millions of years ago before humans, before the ice ages, and when planet earth was warm and humid, forests covered much of the earth.
It was in these forests that abundance of life evolved. The remnants of these prime dense jungles make up the rainforests of today.
