Rainforests

Rainforests disappear, and we all know that humans are the main cause of this destruction. Every year we cut down an area of rainforest the size of New Jersey. Every hour we destroy 6000 acres of rainforest (that's 4000 football fields). What we do not realise is that we destroy the planet where our children and grandchildren have to live. We need the rainforests; they produce oxygen and eliminate carbon dioxide (CO2), cleaning the atmosphere.

But why do the forests disappear so quickly? Well, experts agree that there are two main reasons. The most important is human activity. Big companies cut down more.
