POLLUTION

Each of us desires to live in a clean environment. But in fact, everything doesn't come true as people's hopes. Nowadays, with the development of science and technology, people's lives have been improved and had many positive changes. However, people also face one unexpected issue. It is pollution. This is a really big problem because of its serious effects.

In near future, pollution has had an influence on life directly. In some public places such as: markets, parks, streets,... there are a lot of nylon, plastic bags, papers,... thrown carelessly. These careless actions turn beautiful places into rubbish grounds, and make nasty smells around. Moreover, some sewerage systems are filled up with garbage, making rain-water be blocked and unable to drain quickly when it rains. Therefore after heavy rain, flood, a common matter usually happens, especially in big cities of Viet Nam. The more factories,companies and vehicles appear, the more smoke is released. We don't have fresh air to breathe any more. Also, when some toxic wastes are released, and absorbed into land, water, it is easy to cause severe disease for people, animal, and plant.

Pollution not only causes effects in near future, but also have many other serious effects in farther future, such as: global warming, and climate change. Temperature on the Earth is increasing 0.1 degree every ten years. The Artic and Antatic ice caps will slowly smelt, so the level of the oceans will rise, causing floods in many low-lying part of the world. In addition, when the climate changes, some areas will become wetter while others will become drier. Some areas which today are green and fertile will eventually turn into deserts. Besides, some tropical diseases like malaria, fever,... will get popular in areas where they haven't known yet today.

Actually, pollution is a problem being worth concerning in all countries in the world. People cause it and are also its victim. It effects our lives a lot in present and even in future time. We must realize the importance of environment, have specific actions to protect nature and keep our Earth green.
