The 'Polluted' Ocean

how humans affect the ocean

Oil Spills

Oil spills-about 20,000 oil spills happen yearly, but not all of them are catastrophic. Some oil spills can happen naturally. For example Coal Oil Point along the California coast an estimate of 2,000 to 3,000 gallons of crude oil is released .

Prevention

We can clean up oil spills by helping companies like LAMOR which cleans oil spills using skimmers.

Eutrophication

Eutrophication is the formation of an algae bloom and it decomposing wasting all of the dissolved oxygen in the area. We can cause rapid growth of algae blooms by putting too much fertilizer in our plants which eventually ends up in the ocean

Preventionn

To prevent eutrophication limit how much nutrients you put on your plants, put algae filtration in rivers, and use ultrasonic irradiation. Also you can make an artificial reef to bring back organisms to an area

Overfishing

By overfishing we are losing species as well as entire ecosystems.As a result the overall ecological unity of our oceans are under stress and at risk of collapse.WE are losing a valuable food source that many depend on for social,economical, or dietary reasons

Prevention

To prevent overfishing you can start fishing in specific seasons so that the fish have time to reproduce while your catching other fish.

Introduced species

Introduced species can create more competition for food in an environment.They can bring in new diseases that nothing in the ecosystem are not adapted to,and an potentially disbalance and destroy an entire ecosystem

Prevention

Create mechanisms to prevent introduction in the first place. Create monitoring systems to detect infestation. Move rapidly to eradicate newly detected invaders.
