Help! ... an introduction
Ever since people have lived on earth, they have used animals and plants to give them everything we need. Animals are killed for meat and skin, trees are cut down for paper, plants are uprooted for food, minerals are dug from the ground. We now know that this supply is not endless and if we keep on with our current trends, using nature as thoughtlessly as we are now, how much longer could it last? So nature has to be looked after.
Endangered species exist in low numbers and need intensive long-term management in order to survive. Attitudes toward predators must be changed before we hope to change the present situation. By learning the reasons why species are endangered, students can learn how clean, healthy ecosystems are crucial to life and the consequences of such actions as polluting the environment and destroy habitats.
Taking care of nature means trying to keep a balnce between the needs of people and the needs of wildlife (plants as well). The world has to be shared. We need not to just enjoy looking at them, we need them because they provide us with food and oxygen. If they don't survive, we can't either!
At some point in time, the wisent, the American alligator and tuatara were in great danger of extinction. But they were saved. They are living proof that it can be done. We must do our best to make other animals proof that we still care. We can do it!
