Environmental problems have become one of the most pressing problems of modern society. More and more people are suffering from water and air pollution. Nature also suffers from soil pollution and radioactivity. The reasons for such environmental problems are many. Among them, the increase in the number of cars on the roads, the waste of factories, the millions of felled trees, the destruction of the natural habitat of animals, contaminated rivers and seas. If you look closely, you can see that not only one city is in danger, but most of the world’s population. Fortunately, there are many opportunities to pause these problems. If everyone starts to take care of the planet on which they live, many environmental problems can be solved. For example, if we start recycling paper and cardboard, we will save many trees. If we start using more public transportation, than personal cars, we will have less air pollution. The local government can also help to stop some problems if it prohibits logging enterprises from destroying forests, or stops plants from water pollution. The most important, of course, is to start acting now, or we will face many global catastrophes.
