[originaltext] If the earth gets hotter in the new century, what will happen

If the earth gets hotter in the new century, what will happen to animals and the 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. Global warming, a recent warming of the Earth’s surface and lower atmosphere, is believed to be the result of a strengthening of the greenhouse effect. Because of this, people were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turned their attention to plants and animals at an important meeting. They reviewed evidence that plants and animals are sensitive to climate.Since the Ice Age ended 2,000 years ago, 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 amount in the next 100 years as they did in the past 10,000. Will animals and plants be a-ble to adapt that quickly to change in the environment? Many won’t. Certain species will probably become very rare. Experts say plants under climate stress will 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 the endangered species may become useless as the species are forced to migrate along with their natural homes. Changes are part of life, but rapid change, says scientist George Woodwill, is the enemy of life.
