Pollution
Pollution is a very bad thing because it gives out bad oxygen and do you want to know how it starts ? When there's a lot of cars in the road black smoke will come out from the cars, or factories and how do they go you ask ? Because the trees take the carbon and gives us good oxygen. To help get rid of the pollution you can ride a bike because it doesn't produce carbon.
