These days more and more people have been causing pollution. It may not seem that bad right now but if we keep up what we have been doing in a few years it will be bad. Pollution can be caused by driving your car, throwing garbage in the ocean or even smoking a cigarette. All the bad gas is going up into the air and polluting. The polluted air can go into the trees which give us oxygen, which could kill the trees there for we would have no oxygen to breath. The polluted air could also kill all the plants which would mean less food for us and less food for animals. The polluted air could also get into animals lungs and make it hard for them to breath as well. Next if we put trash into the ocean the fish sharks and other under water animals could eat the trash, choke and die. The fish could also get trapped in the trash and die. Fisherman will also we catching less food which means less food for us to eat. When pollution gets really bad we wont be able to breath or eat. This would result in many sick or dying people and animals.
