Big cities are always densely populated. You will never find a city without any plant or factory. They may produce necessary goods, but at the same time they are the main air pollutors in a city. This can become a global ecological problem if we don't invent the way of cleaning the air.
Plants and factories also pollute water in rivers and lakes. A polluted river loses its "population": fish and water grass, and becomes unavailable for rest and fishing.
While I am speaking about factories I don't except that people are the city polluters too. Nowadays every fourth person owns a car, which also pollutes the air. There are some people who drop litter in parks and even in streets. This litter will not disappear immediately.

Hello Ann.
I am Glad to receive your letter. I really don’t understand why people start to be vegetarian. I think it’s not useful, because our body needs a lot of vitamins. Our muscles can't develop without meat. And if you want to have good health and body you need to eat healthy food, including fruits, vegetables, meat, chicken and drink a lot of water, but not coca-cola or other bad drinks. I Do exercises every morning. That’s why I have good health. And I know that I shouldn’t eat junk food like pizza, hamburgers and food from McDonalds, KFC etc.
