Environmental pollution is one of the largest problems in our todays world. It can be defined as a contamination of air, water and land from man-мейд waste. Nowadays there arent any cities and hardly any rural areas that remain clean and unpolluted.
There are a lot of different types of pollution among which the most recognized are air and water pollution, soil and radioactive contamination, littering, noise, light and thermal pollution. Unfortunately, most of the problems are the result of human activities. Indeed, the contradictions between man and nature are on a high level.
People cut down forests and thus damage thousands of acres of land. First of all, the soil  can be easily blown away and secondly, even if new trees are planted, they cant bring back the old forests that were a part of a complex ecosystem that cleaned the air and мейд home for wildlife.
Big industrial cities produce a lot of waste every day. Its either thrown away or dug up which leads to the releasing of dangerous chemicals into the soil. Very often toxic or poisonous liquid chemicals are poured into the water therefore peoples health is put at risk. However, they are themselves responsible for this.
Water and air pollution are also a serious threat to our environment. The main factors contributing to them are car fumes, oil spills, throwing litter and many others. Polluted air and water affect peoples health to such an extent that millions of them have got no access to safe drinking water.
In conclusion, it must be said that if we want to live in a better and healthier world we should take great care of our mother nature and learn to protect it.
