Air pollution

Dear Maria,

Thanks for your letter. It was great to hear from you.

You wanted to know abaut some of the environmental problems in my country. In my opinion, the worst thing is air pollution. There is too many cars in our citys. If people use their cars less, It wouldn't be so bad.

Last month, I buy a bike and now I cycle to school every day. This is much better for the environment and it keeps me healthy two?
