Read the paragraphs, and then do the tasks that follow.
The loss of forest is destroying the
earth`s plant and animal variety. Scientists say about 5,000 species of plants and animals are eliminated each year. This is especially worrying as many of those plants and animals could be used as medicines against cancer, AIDS, heart disease and many other sicknesses. We never know the true cost of this destruction.
