Ecology is one of the main aspects of our life. Good ecology means strong health and clean nature. Ecology that surrounds me in my native town has many problems. The first of these problems are traffic fumes. There are many cars in my town; today’s fuel makes poison in the air that spoils our oxygen. The second problem is rubbish all over streets: cigarette ends, bags, used bottles; and homeless cats and dogs eat it! The third is too small amount of green outside. We have a lot of houses and different huge buildings, parking places and so little trees, flowers and grass. Green cleans our air and make us be healthier; and I am pity we have not it enough. I consider we should solve these problems unless we will live in the world full of negativity and greyness.
