importance of the rainforest: Effects of deforestation
 
A short summary
The vegetation in the rainforest help to hold the topsoil together and maintain the nutrient level, through biological cycling. Plants absorb these nutrients and they are returned when the plant or part of the plant dies. Flooding itself can cause the destruction of human settlements.The increase in carbon dioxide in the atmosphere is the main culprit of global warming and the greenhouse effect. With global warming, the entire climate of the planet will change, bringing more natural disasters.forest dwellers without food or shelter.

section outlines:

The rainforest contains some of the most interesting product of nature and thus it would be a disaster if they were to be removed. With the increasing rate of deforestation thousands of species of animals will be left without a habitat and many more will perish. What is more saddening is that many of this species have yet to be recorded and studied. Those without a home will be forced into the human society and end up as pest. They’ll eventually be killed.

The vegetation in the rainforest help to hold the topsoil together and maintain the nutrient level, through biological cycling. Plants absorb these nutrients and they are returned when the plant or part of the plant dies. When these vegetation covering are removed, the nutrients in the topsoil are washed away when it rains, and this nutrient will not be replenished since there are now no more trees. In the end the land will be barren, unsuitable for any form of plant growth. The washing away of the top soil often floods the nearby rivers due to the sediments that enter the channels. Flooding itself can cause the destruction of human settlements.

As we all know, plants on the planet help in the carbon cycle, and maintains the level of gases at a constant. With the destruction of large areas of the rainforest, there will be lesser plants to take part in photosynthesis and keep the carbon dioxide level at a low. The increase in carbon dioxide in the atmosphere is the main culprit of global warming and the greenhouse effect. What more, trees that are cut are often burnt or just left to rot. This is further release carbon dioxide into the atmosphere and make matter worst. Global warming, which is now an environmental issue has disastrous effect. With global warming, the entire climate of the planet will change, bringing more natural disasters.

A site all about global warming.  It covers every aspect of global warming from the definitions, to the lastest updates.

Forest clearance will also leave human forest dwellers without food or shelter. They will then be forced to join the human society which is unknown to them. Having existed in the rainforest for thousands of years, the new environment will be hard for them to cope. They will also be prone to modern diseases and many may die.
