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. Directors, actors, and writ The trees of the rainforests help the Earth's air because their leaves use carbon dioxide and make oxygen, which we need to live. its high point in these year They are also important because they control some of the Earth's weather. Through they give out water vapor which makes heavy clouds. The clouds then move to other parts of the Earth and give rain. The clouds also protect the Earth their large leaves, from the sun. (ウ) 日 moved to like Today, the Earth is slowly getting hotter, and in some places changes in the weather are making life much more difficult. We need to learn more about the Earth's weather while we still have the rainforests. and see the golden
