Tapescript: DISAPPEARING ACTS At the moment, the world is losing species of wildlife almost every day. The two main causes of this decline are the destruction of their habitants and overpopulation by human beings. Every minute of the day, 20 hectares of tropical rainforest are cut down or burned. Hundreds of wild species – insects and plants – are lost as a result. If it goes on, rainforests could disappear in 50 years’ time. They are vital in keeping the Earth’s climate and environment stable. If they are destroyed, mankind will suffer as well as wildlife. As cities grow and industry develops around them, pollution becomes another problem for wildlife. Friends of earth believe that two-thirds of the world’s population will be living in urban areas by the year 2025. Something must be done! In theory, most countries agree that there should be no trade in endangered species.
