At first i would like to say that ecological problems are the one of the most serious nowadays. Because of humans our planet is dying of pollutions. Even now many speeches are dying of waste from fabrics. In my city air and water pollutions are serious problems. Because of them people can get or even things worse could happen. Because of air pollution ozon layer above our city is destroying. It can cause radiation from sun to hurt all human race. I also think that people should help our planet to live longer. We should keep our planet in good shape for our children. For this we should use recyclable things instead of plastic that decompose up to 1 million years. At the end I wold like to say that the less we harm our planet the better it would be for our descendants to live on it.
