A green Earth or a dry desert?

For millions of years, the tropical rain forests have been the hearth’s natural chemical laboratories, botanic gardens and zoos.

Much of the food, medicines, and materials we use today are derived from the wild species that grow in the tropics.

Today we are destroying them at such a rate that, in a future not so far, only fragments will remain of the vast forests. Plants regulate the atmosphere, maintain water supplies for agriculture and prevent the formation of deserts. When many trees are felled, soil erosion begins and, within a few years, the whole area that was once forest becomes wasteland.
