What we should do to prevent climate change.

Nowadays in a lot of cities air pollution has become one of the biggest problems. Residents who have heart diseases suffer more than most other people do, but high level of contamination causes problems passively when we just hurry up on to work or go out with our babies for walking. However, there are some simple solutions, which we can do, to reduce the risk.
Firstly, we should use cars less than we use. It will help to put down air pollution. More preferably If you can afford to buy a hybrid car, that would be better, but they [hybrid cars] have a high cost at the moment. So, you can use your bike instead.
Secondly, it would be good if everybody of us would plant a tree in his or her villages or dachas. I think if we plant at least two trees it will help to protect our planet, and the environment will also be grateful for you.
Finally, we must teach our children for those simple steps. Because our children are our future!
In conclusion, I believe that the government will also manage this situation because a lot of factories at the moment predominate entertainment a lot, so only severe law and penalty will stop them.

Very well done! The errors were few in number and minor. Молодец!
