Plants help clean air so therefor planting gardens will help reduce pollution. Another thing you can do to prevent air pollution is walk or bike or even the next time your parents need to get a new car persuade them to get an electric car because it does not release gases into the air.

One of the many reasons people shouldn't put pesticides on there lawn is because when it rains pesticides are washed into streams and the streams become unhealthy and more algae grows suffocating fish and poisoning them. Another way people make water unhealthy is when they litter and the litter is washed into streams.
