There are a lot of ecological problems. The first big problem is water pollution. Factories are polluting rivers and lakes of my country with very dangerous chemicals. Tons of industrial waste are poured into waters. It will be dangerous to drink water and to go swimming in summers if we won't do something. The second problem is air pollution. Plants and factories emit harmful smog. Cars are very popular nowadays, but they pollute the atmosphere. They are giving off dangerous fumes. A lot of people have breathing problems. Не уверенна, что тут есть 120.
