One of the problems is pollution. The air is polluted because of car fumes. It makes we feel ill and we have sometimes problems with breathing. What can we do to prevent it? First of all we should leave our cars at home and use our bicycles or walk more often, so cities would be less polluted.
In cities are less green areas. If we had more trees, we would have more oxygen. The authorities should create more parks. I think that would be good sollution. Also for children, who would be able to play safely.
Third of problems is rubbish. We should always throw our litter into bins. In my opinion the authorieties should put bins on every street corner. Other sollution of this problem is recycling. We should recycle our needless things. As a result there wouldn't be so much rubbish everywhere. And these 'needless things' could be used again instead of thrown away.
To same up, if we want make our cities more environmentally friendly, we can do it - it's easy!
