Ocean Conservation

This is a section of the Great Barrier Reef along the coast of Australia that shows the effect of El Nino and how it is spreading the warm trade winds across the Pacific Ocean causing a disruption in temperature.

WHAT'S HAPPENING...

NEGATIVE HUMAN IMPACTS ON MARINE ENVIRONMENTS

OVERFISHING

POLLUTION

CORAL BLEACHING

OCEAN ACIDIFICATION

OIL SPILLS

HABITAT DESTRUCTION

OVER FISHINGOCEAN ACIDIFICATION

Workers clean up an oil refinery spill that polluted Anacortes Bay, Washington. The floating ring of absorbent pads trailing behind is used for absorbing and containing some of the oil that was spilled.

Pollution, logging, dredging, and the draining of wetlands, and coastal development are all factors that lead to habitat destruction. This pictures shows the absence of the Cypress swamps decimated by logging and saltwater intrusion from man made canals.

This picture represents how much us humans care about marine life. The definition of overfishing is when more fish are caught faster than they can reproduce. Many species and the environment depend on these fish and we are just do not care or are ignoring the situation. Many fisherman are working to cut down on the amount of fish they catch, but there are still illegal fisherman fishing all around the world. We need to help reserve these fisheries and help create more marine protected areas.

Ocean acidification occurs because too much carbon dioxide is released into the atmosphere. With the increase of CO2 the ocean's pH level is compromised and the ocean no longer has a stable supply of certain minerals that in turn affects the organisms that need to form their shells to survive. To help, we can reduce or energy and electricity usage.

Oil spills often occur when humans mine the ocean floor for it's raw materials and we either spill or leak. It also occurs from storm water drainage from cities, farms, factories, and boats. When oil spills into the water, it affects the environment around it including the many organisms that live nearby. It can cause erosion and contaminates the water especially along the shorelines. To get rid of the oil spills, humans have turned to biodegradation and bioremediation which will help accelerate the rate of the biodegradation. In order to prevent more oil spills in the future,a law was passed in 1990 called the Oil Pollution Act of 1990 which provides cleanup funds for oil pollution incidents.

OIL SPILLS

One of the main ways humans have destroyed the ocean is by polluting. 80% of the pollution that enters the ocean is from land runoff. Pollution can occur from trash buildup, acid rain effects, improperly disposing of chemical wastes and many other ways.Many organizations are working on controlling the amount of pollution that enters the ocean such as the EPA, USACE, and USCG. They work to prevent ocean dumping and protect marine life. Humans can help prevent pollution by properly disposing of chemical wastes, recycling any papers, plastics, or glass, and most importantly, being fully aware that pollution is a worldwide problem that we need to solve together to preserve our beloved oceans.

POLLUTION

Habitat destruction occurs when the necessary condition for organisms are compromised or eliminated. This especially happens along highly populated coastal areas. Inland dams decrease natural run-off and cut-off fish migration routes. Deforestation can cause erosion that blocks out the sunlight coral reefs need to survive. Laws have been put in place to reduce garbage dumping and other sewage issues but scientists agree that drastic measures will be needed to solve this problem once and for all. Warmer water temperatures will cause algae living in their tissues to leave them, bleaching the coral bright white. In 2005, the U.S. lost half of its coral in the Caribbean in one year to coral bleaching. The warm waters around the northern Antilles had migrated south and causing the algae to stress. If you want to help this cause then conserve your water. If the usage of water goes down then there will be less runoff and wastewater polluting our oceans.
