Tons of harmful gases emit to the air everyday. Factories have caused this problem. We need to do something fast before our city doesn‘t become deserted.
Firstly, we have to create industrial park. It will help to reduce factories in the cities, where a lot of people live.
Another solution is to start stricting the laws. If the laws be very strict, then less and less persons will be able to get a license for the new factory.
Finally, we should renovate our factories. Modern plant emit less unhealthy gases. This would allow us to start a policy, which will help to clean our environment.
In conclusion, there are many ways to make our cities a better place to live.
