Since ancient times Nature has served man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But with the development of civilization man’s interference in nature began to increase.

Every year world industry pollutes the atmosphere with about 1000 million tons of dust and other harmful substances. Many cities suffer from smog. Vast forests are cut and burn in fire. Their disappearance upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.

The pollution of air and the world’s ocean, destruction of the ozone layer is the result of man’s careless interaction with nature, a sign of ecological cities. Environmental protection is of a universal concern. That is why serious measures to create a system of ecological security should be taken.


Our planet Earth is only a tiny part of the universe, but nowadays it's the only place where we can live. People have lived on our planet for many years. They lived and live on different continents, in different countries. People depend on their planet, the sun, animals and plants around them. Environment is everything in the world around us that surround and affects all life on earth, including the air, food, water, plants, animals and other.

Environment is the place where we live. Since ancient time nature has served man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But man's interference in nature began to increase with the development of civilization. Our ecology becomes worse and worse with every new day. Many species of animals and birds are disappearing nowadays. People destruct wildlife, cut down trees to make furniture. They forget that people can't live without trees and plants, because they fill air with oxygen.

There are a lot of ecological problems. The most serious ecological problems are: noise from cars and buses; destruction of wildlife and countryside beauty; shortage of natural resources; the growth of population; pollution in its many forms. Water is everywhere, but there is no ocean or sea which is not used as a dump. Many rivers and lakes are poisoned too. Fish and reptiles can't live in them. People can't drink this water. So we have to clean the water environment.

Another problem is air pollution. Air pollution influents the health of people. For example: ultraviolet radiation from the sun can cause skin cancer. Normally the ozone layer in the atmosphere protects us from such radiation, but if there are holes in the ozone layer ultraviolet radiation can get to the earth. Many scientists think that these holes are the result of air pollution.

Also we have problem with nuclear pollution. Nuclear pollution cannot be seen but its effect can be terrible. To make air clear clean again we need good filters at nuclear power stations, at factories, in cars and buses.

Water pollution is one of the famous and one of the largest problems in our world. People in Africa cannot drink clean water; their children die because a big part of our water has been polluted. Children in Kenya often have to go many kilometers to collect drinking water. At all over 2 million people don't have clean water. And we do not know how it will be in future.

But the pollute water killed animals and plants too. There is no ocean or sea, which is not used as a dump. Many seas are used for dumping industrial and nuclear waste. This poisons and kills fish and sea animals. "Nuclear-poisoned" fish can be eaten by people.

Many rivers and lakes are poisoned too. Fish and reptiles cannot live in them. There is not enough oxygen in the water. In such places all the birds leave their habitats and many plants die. If people drink this water they can die too. It happens so because factories produce a lot of waste and pour it into rivers. So they poison water.

But we must keep our planet and water of our planet clean. If we want to live, we should guard our clean water and do not pollute them because we could live without food about a month but without water we could die in 4-5 days. Let's keep our water clean!

Another problem is growth of population. They don't have enough places to live. They need more water, more food. So it is the reason of the shortage of the natural resources. It is very difficult to solve this problem.

In addition, not many people understand that they are polluting environment. They are dropping litter on the streets. In my opinion drop litter or rubbish in the dustbin isn’t hard, it’s easy.

Also one of the most serious problems is greenhouse effect. It works like this: sunlight gives us heat. Some of the heat warms the atmosphere and some of the heat goes back into space. Nowadays the heat can't go into space. That's why winter and summer temperatures in many places have become higher.

If the temperature continues growing up the snow on the mountains and ice will melt, so the most of the earth will be under water. So every person has to understand how important it is to solve these problems, which endanger people's life.

The world is getting hotter because of us! When the sun shines, everything gets hot because the hot air has nowhere to go, everything gets hotter.

Our world is warmer than it was one hundred years ago. Hot countries may become drier and the people who live there won’t be able to grow enough food. Ice in cold areas is changing to water because of higher temperatures. When this happens, the sea levels become bigger. Some towns near the sea may have a problem soon.

We can help if we stop making the air dirty but we must do something fast!
