Write a paragraph about air pollution by answering the question below.

**AIR POLLUTION**

Air pollution happens when the air gets filled with bad gases like carbon dioxide, carbon monoxide, and other harmful stuff. This is a bigger issue in big cities and places with lots of factories. In big cities, there are many cars and trucks that make bad gases. Also, factories and mills make smoke, gas, and other bad things. Sometimes, trash and dead animals left out in the open can also make the air dirty. 

To make air less dirty, we need to tell people about it. Newspapers, radio, and TV can help with this. We should have strict rules so that vehicles that aren't good for the air can't be on the road. They need a paper saying they are okay. People who don't follow the rules should get in trouble. Police who work with traffic and other groups need to learn how to handle this. 

More people moving to cities and making slums can also make the air worse. Groups that aren't the government can help with this. The government can also make jobs in villages so people don't need to move to cities. We want cities to be clean and healthy, so we need to stop air pollution. I hope my city becomes free from dirty air.
