why should we save the amazon rainforest
The importance of the Amazon rainforest for local and global climate Tropical forests and woodlands (e. g. savannas) exchange vast amounts of water and energy with the atmosphere and are thought to be important in controlling local and regional climates. Water released by plants into the atmosphere through (evaporation and plant transpiration) and to the ocean by the rivers, influences world climate and the circulation of. This works as a feedback mechanism, as the process also sustains the regional climate on which it depends. The Amazon rainforest could cure you What is the connection between the blue-green pills in your bathroom cupboard and the Amazon wildlife? The natural roots of medicine. For millennia, humans have used insects, plants and other organisms in the region for a variety of uses; and that includes agriculture, clothing and, of course, cures for diseases.
Indigenous people such as the Yanomamo and other groups of mixed ancestry (e. g. the
mestizos of Peru or the caboclos of Brazil) have perfected the use of chemical compounds found in plants and animals. Knowledge of using these plants is usually held by a medicine man ( shaman ), who passes on this tradition to an apprentice, a process which has been ongoing for centuries and that forms an integral part of peopleБs identity. With rainforests going fast, the continuity of this knowledge for the benefit of future generations is under threat.
Untapped potential of the Amazon's plants Scientists believe that less than half of 1% of flowering plant species have been studied in detail for their medicinal potential. As the slowly shrinks in size, so does the richness of wildlife found in its forests, along with the potential use of plants and animals that remain undiscovered. Laurance, W. F. 1999.

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.
