Air pollution in china is caused by MANY factories which make lots of the food we buy from the supermarket.
|People wear masks to protect them from the pollution so they do not breathe in bad air. People get very sick|
|Factories burn energy to make their machines work - such as petrol and coal. This is bad for our environment|
