Transcript of Sea pollution
Disposed plastic is one of the biggest problems we face in our ocean today. The toxins the plastic carries are affecting us all; humans and sea creatures! Sewage Sewage affects the ocean and the creatures in it. Sewage is the waste from household toilets and sinks that gets poured directly from the sea. The sewage builds up harmful bacteria that can bloom. This can make sea creatures like dolphins get ill. Some dolphins have visible bacterial infections on their skin, this might be caused by overload of sewage. Toxic wastes Toxic wastes are materials that are poisonous and is a type of pollution that is being disposed into the oceans and seas. Toxic wastes affects both marine(water) life and human health. Toxic waste is the biggest threat to the ocean. Toxic wastes come from leaking of landfills, dumps, treasure (usually gold) mines and farms are also having the same trouble of toxic leaks. Garbage dumping Garbage dumping is the disposing of harmful materials into the ocean. Human waste, ground-up garbage and water from bathing are kinds of garbage that is being dumped in the ocean. People started dumping most of the waste in the ocean since 1990's. One main cause of garbage dumping occurs when sewage pipes mix up with the storm water drains. Rainfall will cause the sewage pipes to overflow forcing the sewage waste to mix with the rain water and that waste is flown into a lake or river. This will pollute the water and kill the animals and plants in the water too. In the ocean, one toxic organism gets eaten by an animal, then it is eaten by another animal on top of the food chain and it eventually becomes our seafood. Lead is one of the most harmful chemical in the ocean. Lead is capable of damaging the brain, kidneys and the reproductive system. Lead can also lead to birth defects for human beings. It has been shown to cause low IQ scores, slow growth and hearing problems for small children Cars Some people may have not noticed but cars pollute the ocean. When you drive you may have noticed that there is smoke coming out of the back of the car. The smoke dosn't go directly to the ocean, instead it goes in the air. When the pollution mixes with the water in the clouds it form acid. When the acid starts raining this is called acid rain. Acid rain is a mix of pollution and water, when acid rain gets in the ocean it pollutes the ocean and it also kills many fishes over a period of time. This also happens when factories release pollution into the air. See that! All of these things are affecting our oceans and seas. Each of us now thrash at least 1500 pounds of rubbish a year and yet the fraction waste dumped in the oceans and seas is going to nowhere but up. If we all stop polluting the ocean and seas, to take action, but if we don't stop all kinds of pollution from happening... Our world is going to end... By Matthew
