VI. Choose the best answers.

Rainforests circle the globe for twenty degrees of latitude on both sides the equator. In that relatively narrow band of the planet, more than half of all the species of plants and animals in the world make their home.  Sever hundred different varieties of trees may grow in a single acre, and just one of those trees may be the habitat for more than ten thousands kinds of spiders ants, and other insects. More species of amphibians, birds, insects, mammals and reptiles live in rainforests than anywhere else on earth.

Unfortunately, half of the world's rainforests have already been destroyed and at the current rate, another 25 percent will be lost by the year 200. Scientists estimate that as many as fifty million acres are destroyed annually. In other words, every sixty seconds, one hundred acres of rainforest is cleared. When this happens, constant rains- erode the former forest floor,  thin layer of soil no longer supports plant life, and the ecology of the region is altered forever. Thousands of species of plants and animals are condemned to  extinction and since we aren't able to predict the ramifications of this loss o a  delicate global ecology, we don't know what we may be doing to the future the human species as well.
