For the last years, our planet became dirty and polluted place. I think there are many things we can do to make our planet cleaner and healthier place.
The main problem is a terrible traffic which causes air pollution. I think people should stop using their cars so often. If governments improved public transport, more people would leave their cars at home. People should also use their bicycles. This would reduce the number of the cars on the roads and our cities would be less polluted.
Another big problem is an amount of litter on the streets.
If the authorities put bins on every street corner, perhaps there wouldnt be so much rubbish.
Finally, I think there are too many buildings and not enough green areas. The governments should stop building so many houses and offices. If there were more green areas and trees in our cities, people would have more oxygen. If we had more parks, children would be able to play safely.The result would be a more pleasant environment which would help everyone to relax.
These changes would reduce pollution and make our cities cleaner places to live in.
Вот, надеюсь помогло :)
