听力原文： If the earth gets hotter, what will happen to animals and plants which animals depend on for survival? The question offers another way of looking at the 'Greenhouse Effect'. People have talked about the general problem of 'Global Warming' for some time. But they were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turn their attention to plants and animals last October. They review evidence that plants and animals are sensitive to climate. Since the Ice Age ended and warmer temperatures returned to the northern latitudes, many species have migrated north. If the predictions about the Greenhouse are correct, temperatures will rise by the same a-mount in the next one hundred years as they did in the past ten thousand. Will animals and plants be able to adapt that quickly to change in the environment? Many won't. Certain species will become rare. Experts say plants under climate stress will be very open to disease and fire. Forest fires may become more common. That, in turn, may harm animals that depend on the trees for food or shelter. Any preserves we set up to protect endangered species may become use-less, as the species are forced to migrate along with their natural homes. Change is a part of life, but rapid change is the enemy of life. What is the concern of ordinary people about the 'Greenhouse Effect'?
