When it comes to mixing oil and water, oceans suffer from far more than an occasional devastating spill. Only about 5 percent of oil pollution in the oceans is due to major tankers.
Not only are the oceans used as dumping grounds, but they have recently become the source for materials that by their removal, could have serious consequences
Metals and slowly degrading chemicals threaten inland and coastal watersIndustrial, agricultural, household cleaning, gardening, and automotive products regularly end up in coastal waters.
Trash can killWhen odds and ends of life on land-- particularly plastics--end up in the sea, they can harm marine life when they are mistaken as food or entangle animals.
Marine Pollution II
American water sheds
Identifying a water polluter is a snap when you spot a single pipeline spewing wastes. A wide range of activities contribute to nonpoint source pollution.
Non-native species are introduced to new areas through ship ballast water and other means, and often cause ecological problems.
More than three-quarters of ocean pollution comes from landMuch of it flows into the oceans from the mouths of rivers.
Raw sewage from combined sewer overflows and other sources poses health risks and contributes to oxygen depletion in coastal waters
Nets are not always selective: some scoop up everything in their pathsCommercial marine fisheries in the U.S. alone toss away up to 20 billion pounds of by-catch each year--twice the commercial and recreational catch combined.
Most of the world's commercially important fish species are fished to capacity or depleted
Overfishing has social and ecological consequences
Bombs, poison, and scrapers damage habitatsCyanide, blast fishing and bottom trawling alter fish habitats and kill non-target species.
Bad Sports And tourist traps
Dams and diversions
Habitats in harm's way
Droves of tourists and water-sports fans descend on and into tropical and coastal waters. All too often they leave damage in their wake.Sea-floor and shore sights suffer from overexposure
Clearing inland forests harms coastal ecosystems in the tropics and temperate areasDeforestation affects marine life
Coastal wetlands worldwide are being lost due to drainage, dredging and filling.Coastal wetlands are disappearing
Dams and diversions of fresh water alter fish habitat, rob downstream areas of nutrients, and raise salinity in coastal waters.Coastal ecosystems suffer when river water is diverted
Swarming the shores
Stratospheric ozone depletion could have ecological effectsLike falling dominoes, each level in the antarctic food web could be affected by increased ultraviolet radiation.
Congested CoastlinesAs coastal populations grow, development threatens wildlife and coastal ecosyatems.
Oceans are crucial in shaping climateOceans store and move heat around the planet, and they're a major source and storehouse for gases that affect climate.
Growing human population place demands on coastal resourcesOver half of the world's population lives within 60 miles of a coastline.
We Need to take care of our ocean and try to reduce the amount of trash exponential amount but it all starts with one person who dosen't litter, and saves water or dosen't pour oil down the drain or makes sure there car gets fixed when your leaking oil and supporting a solar future and clean
