Endangered Species


Some animals and plants in our world are very common, like houseflies, cats or daisies. They are not in danger of dying out. Other species are very rare. Sometimes only a few of them are left. Such species may disappear forever.

Ever since life on earth began, animals and plants have died out and new ones have appeared. Dinosaurs, for example, roamed the planet during the earth’s middle ages. 65 million years ago, they disappeared forever.

Animals and plants need each other to survive. They keep the world of nature in balance. If a certain plant dies out, some animals may become extinct too, because they depend on the plant for food.
