Problems of the planet

Do you love your family, friends and relation? Of course, you love them. But why do not you save our planet? Nowadays, we see from television or read from newspaper that our planet is going to be an intolerable place to live. I believe that the earth is being damaged by many things especially human activities.

There are still many problems of the planet in recent years. One of the most important problems is the deforesting. Forests are home to hundred of species of flora and fauna. While cutting down the trees for a paper or to make furniture, people forget that they are also cutting down our supply of oxygen, water and plants. Because trees absorb the carbon dioxide which is bad for health, effects changes in the climate and raise the temperature. Due to the fact that carbon dioxide increases and ply of ozone is punctured. We have seen the consequences of upsetting this balance in many environmental problems such as global warming. As the earth’s temperature rises, the icebergs in the south polar and north polar melt and the sea level becomes higher than before. Where do animals and birds go after cut down forests? Nowhere, they die as lose their homes. Also the rivers become shallower. If we continue this, there will become more problems in the earth.

Another serious problem is pollution of water, air and soil. Water pollution is caused as factories pour dirty water or chemicals into rivers and lakes. Consequently, animals which live in sea, river and lakes are decreased and die. Causes of air pollution are fumes of factories and cars. In recent decades, due to those pollution, ranges from increased allergies, respiratory disease, and cancer to the disorder of the body’s hormone.

Animals are a necessary part of our lives on Earth. But nowadays, more and more people are killing animals to use their skin, fur and teeth etc. So those animals are decreasing day by day. If the endangered animals are not protected the existence of humans will be in danger. Our history has shown that if we continue to exploit our resources, particularly by destroying the land and therefore the natural habitat of plants and animals, we will ultimately harm ourselves.

In conclusion, most people do not know they are destroying nature themselves. So we realize it and try to make environment better place to live. We should use environmentally friendly cars, do not cut down forest and preserve animals. Also government should pass law and spent more money for save planet. If we can do it, our planet will be more safer and healthier.

By the year 2050 pollution levels in cities will have decreased because scientists will have invented environmentally – friendly cars. However, there will be no more rainforests as we will cut them all down. Furthermore, people will live in cities under the sea since normal cities will have become too crowded. On the other side, people will live longer as scientists will have cure for many diseases. In addition, we will go on holiday to other planets because space travel will have improved. What is more, we will do more creative jobs because computers will have done the most boring jobs. But there will be more poor people as there will have been fewer jobs. Moreover, crime will have increased as more people without work.
