Nowadays environmental issues are widely debated. Some people think that pollution is the biggest problem caused by humanity, whereas do not agree. They believe social problems are more dangerous.

In my opinion, the environmental contamination is the biggest threat caused by people. First of all, air pollution is an extremely important issue for everyone. For example, factories and cars emit toxic substances into the atmosphere. People breathe in polluted air and as a result they suffer from health hazards. Secondly, water pollution is caused by people who throw garbage and dispose of waste in water. Therefore, polluted water has a bad impact on life as well.

However, there are beliefs that pollution is a minor threat to the population. Some people claim that social problems are more significant. There are such problems as poverty, unemployment, child neglect. More people die because of the lack of food or sanitation rather than polluted air or water. What is more, unemployment leads to an increase in the number of serious crimes.

Personally, I cannot agree with the opinion mentioned above. Firstly, ecological problems can be imperceptible for a long time, but one day they will emerge and cause a greatest damage in the world. In addition, social problems can be easily solved by governments, while high  pollution makes people breathe dirty air and drink polluted water. 

In conclusion, I would like to say there are opposing views on this issue. At first sight social problems are the biggest threat to society, but in actual fact pollution of nature is the biggest danger. Thus, I strongly believe that pollution is the greatest problem caused by people.
