Reading Sample 1- THE AMAZON RAINFOREST (B2) (Short Reading)



The Amazon Rainforest

The Brazilian tropical forest in the Amazon Basin covers almost two million square miles and constitute about 35 percent of the complete world rainforests. Scientists believe such forests play an important role in controlling the level of carbon dioxide in the atmosphere. Plants take in carbon dioxide and give off oxygen. Plants also store carbon dioxide, which is released into the atmosphere when plants decompose or are burned. For this reason, environmental scientists are worried that clearing the tropical rainforest will cause a high increase in atmospheric carbon dioxide. Some studies have put forward that a global rise in atmospheric carbon dioxide could cause a low warming of the planet in a phenomenon called the “greenhouse effect”. The tropical rainforests are also regarded as some of the world’s richest reservoirs of plant and animal life. Some researchers have estimated that the forests contain up half of all species of life, many of which have yet to be studied.
