POLLUTION

The world is more and more polluted. It is a serious problem because pollution effects badly on human. Thus, we need understand clearly about its causes and effects. First of all, we have to know its definition: Pollution is to make impure; to contaminate an environment especially with human made waste. pollution is comprised of many different categories. They are  Air pollution, Ground pollution, Water pollution, Noise pollution. Air pollution is defined as the bad air we breathe in. Air pollution is found in both indoors and outdoors. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals. Ground pollution is the trash and other material that seeps into the Earths surface. Water pollution occurs when a body of water is affected due to the addition of large amounts of materials put into the water.  When it is unfit for its intended use, water is considered polluted.  Noise pollution is unwanted or offensive sounds that unreasonably intrude into our daily activities. They are all spreading out nowadays, so what are the causes and the effects of this condition?

The waste from the modern industry is main reason of pollution. Day by day, people discard a lot of kind of waste such as garbage, smoking, dust and other toxic waste …. All kind of this waste are dispersed to everywhere and make pollution. Destroying forest has a part in pollution, too. There do not have verduces to filter air so the condition is more and more serious.

The clearest effect is on temperature. 30 years ago, it has increased 0.5-0.7⁰C every decade and the speed has been faster and faster. Thus, how long human can live on the earth? This effect is really dangerous to human. The second one is on air and water. Toxic smoking and waste from factories makes the air and water source has been polluted seriously. Human, plants and animals have to breathe and drink to be. However, the things they receive are harmful ones. The most baneful effect is on our health. Cancer, gene mutation …. and a lot of bad effects on life. More and more people catch strange diseases. Therefore, pollution is really a dangerous problem to human.

All in all, this matter is very serious. Each of us has to have responsibility to change and delete this problem. It belongs to our awareness. Although this is a big problem, I believe that we are able to solve with it.
