Слайд 3Deforestation
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.
Слайд 4World Rainforest
The world’s great rainforest are all near the equator, in
Africa, South America and South-East Asia. Three quarters of the world’s species live in the rainforests. If we destroy their habitat many of them will not survive.
Слайд 5Amazon Rainforest
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.
Слайд 6Benefit of rainforest
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.
Слайд 7Results of deforestation
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.
