.if mankind pollutes water,there would be no safe drinking water for them to drink,plus water pollution can kill the living things in water.
.if we continue land pollution,one day there would be no proper land for us to build houses on.
.Air pollution can damage the air we breathe.If we inhale that bad air..it can sometimes give us diseases.it can Also kill.
Pollution can cause Great damage to humankind and other living things.
