Answer 1

I was told that swimming is good to strengthen the lungs of people with asthma. But the emvironment is what is making it worse.Polution and the things people put in the air , chemical plants really contrubute to ruining the air which it makes it harder on people with asthma. I think indoor green plants in the house will help clean the air inside. Plants outside help clean the air too, and in cities, the more houses go up the more trees go down, and that is ruining our air supply.Also, the machinery ran with gasoline.
