To my mind if we want to impove living conditions in our city we need to switch on our brains and think. Nowadays we live in fast moving world so there is less time think about conditions we live in. Firstly we need to reduce water pollution. It means we sholdn't throw out into water litter and domestic waste. Also big factories shouldn't pour their waste into rivers. Another problem is air pollution, there are many reasons which cause it. Such as car fumes and reeks from factories. I think it will be good to reduce the amount cars in our city. All in all the environment we live in have a stron influence on our health. Today manypeople suffers from various illnesses due to conditions we live. I am sure that people will solve this problem.
