The first and most common animal affected by water pollution, is fish and seshfish. Shelfish filter large amounts of water though their bodies absorbing food and oxygen and cleaning out any waste and toxins they have in their bodies. When the lobster boats, and other boats go through the water and dispose of toxins into the water, it is killing many of the shelfish that live in that habitat.
Also the gas from the boats that leaks into the oceans, such as the busy Pacific Ocean, the gas gets into the fish and shelfish body systems and will evently kill them. The biggest type of water pollution is cause by acid rain. Acid rain is a result of industries and autoa burning oil and coal(fossil Fuels) for fuel. The Acid Rain stays in the air for days and then falls into the Ocean, causing many shelfish to die. When the acid rain falls into the water the fish breath it in and i gets into their body systems and kills them.
Sewage is another thing killing the animals in the Ocean. The sewage that comes into the ocean is very toxic and again when the shelfish and fish go to get food, the sewage will be all over their food and where they live and ruin their enviroment and kills alot of fish.
Finally another major problem that is killing the sealife, is when dumps, and other people dump trash into the ocean, things like that, the animals can choke on and die. When plastic iteams get thrown into the ocean the toxins in it will also make many sealife sick and cause many of them to die.
When things like this happen, it makes the population on fish and shelfish go down. Some people depend on fishing and lobstering for a living, but if people keep polluting the oceans and local rivers, some people will be out of jobs, and wont have money or food to feed their families.
So everyone has to work together to try and stop water pollution. For the sake of the animals in the Oceans, and for the sake of other peoples jobs. Do something about what is going on around you. Throw you trash in the garbage can, recycle your plastic bottles. Save the lives of animals around you. Stop water pollution.
