wal Rainforest trees are used to make things which we use every day. Rubber, for example, is used to make many things. The fruits of many forest trees ( 7 ) — forest people have eaten them for thousands of years. Today, all over the world, people eat rainforest food plants; for example, coffee, tea, oranges, and rice. Corn, which is an important food for many people of the world, is another rainforest plant. In 1970, a disease destroyed half the corn in the United States of America. Scientists began to look for new species in the rainforests. In 1987, in the Mexican rainforest, they found a new species which is stronger than other species. But we nearly lost this new species, because people were already cutting down that part of the Mexican rainforest. Hollywood, Los Angele movie stud (1) knows how many useful plants are already lost because people have SHOULD destroyed many of the rainforests of the world.
