2)some people’s activities do a lot of harm to the forests. people cut down trees to build houses, roads, factories and plants. deforestation is a very serious environmental problem. the world’s great rainforests are all near the equator, in africa, south america and south-east asia. these rainforests are homes to millions of kinds of exotic animals, birds, reptiles, insects, strange plants and beautiful flowers. three quarters of the world’s species live in the rainforests. if we destroy their habitat many of them will not survive. amazon rainforest is the biggest and most important in south america. scientists believe that plants from the forest could give us many important new medicines such as cures for cancer and aids. the rainforests also help to reduce pollution levels in the atmosphere and affect the weather around the world. without rainforests our planet might not survive. people know it but continue to destroy rainforests every day. logging companies cut down trees to sell the wood, farmers clear the land to grow food crops, people build towns and roads where the forest used to be. vast forests are cut and burn in fire. their disappearance upsets the oxygen balance. as a result, a number of rivers and lakes dry up, some rare species of animals, fish, birds and plants disappear forever. people should take measures to reduce the amount of deforestation and protect the flora and fauna of the rainforest. our planet is our home and we need to protect it.
