Global warming is one of the major environmental problems we are facing today. Scientists think a further rise in the carbon dioxide levels will make this situation worse. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperature. This, in turn, has an effect on various plants and animals. Global warming makes it difficult for some of them to survive.
Water pollution is caused when wastes are thrown into water. What’s more, many harmful chemicals are also put into water, which endangers people’s health and many wild animals die out.
The increasing population is causing a loss of natural resources. This is related to various human activities. For example, over-fishing has caused many kinds of fishes to die out. Forests are being cleared to meet the rising demand for paper, wood, even for land. Mining, the work of getting gold, coal etc out of the earth, has led to a further drop in mineral resources. If we used up all the resources, how could our children survive on this planet?
These are some of the environmental problems now. Only with an effort from each person, can we hope to save our planet from being destroyed.
