Hello my friend, I want to tell you about my city environmental problems and how you can get rid of them.I believe that the main problems of my city is the pollution of water and air. To get rid of this, you need to smoke less, instead avtobiley often ride bikes and do not pollute rivers, lakes. We need to take the old magazines and newspapers, plastic and glass bottles for recycling. So we will save more trees and fresh air.Another problem is the pollution of the streets of Minsk. To prevent this from happening, you need to throw garbage in the garbage cans, not on the ground.I think that Minsk is not a lot of environmental problems, compared with other countries. And our city is more contaminated due to human. I believe that if together we will take care of the nature, we will make Minsk clean country.
