What is Coral Bleaching? Definition: the release of the symbiotic colored algae normally living within coral animals, which occurs when coral animals are stressed (by high temperatures, for example) and makes the coral appear whites. Symbiotic Colored Algae: Zooxanthellae: Gives color and protection for the coral reef along with there ability to live and thrive. They assist the coral to produce nutrients. Without this their physical appearance would be clear.
Global Warming Definition: Depletion of the ozone layer and warming of the planet. Causes: Factories, Trucks/Cars, Deforestation, ect. They admit chlorine through industrial produced CFC’s of gas. Raises temperature within the atmosphere and lets in ultraviolet rays from the sun. CO2,CH4, CFC, NO cause infrared rays to get trapped in the atmosphere.
Consequences of Global Warming Ultraviolet rays that reach Earths surface cause coral bleaching. The temperature increase causes coral bleaching.- As little of an increase of 1 degree Celsius can cause coral bleaching. 1,000 species could potentially lose their home. Ice is melting- Polar bears have little habitat and a great loss of hunting grounds. Heat exhaustion is affecting them also. - They will go extinct within the wild within the next few decades.
Pollution Chain 80 % of marine pollution comes from land based activities. Pollution deposits in the waters and estuaries Build up there concentrations, become toxic Become part of marine food chain Don’t care till human casualties
Where Else Does It Go Doesn’t stop and stay in water Many currents take it for a ride Wind moves rubbish around real good Washes ashore on coast line Pollutes land to the sea, and back to the land Never ending battle with an enemy that cant quit without human action
Where does it come from Only 2 % of hydro carbon pollution comes from tanker accident 11% is from natural sources (tar-sands, oil seeps) 13% comes from the atmosphere 24% comes from all forms of transport 50% comes from drains and rivers leading into the sea - US National Science Foundation
Seems small Tankers accidents may only be 2% But in 1967 - Torrey Canyon ran aground off the English channel - 106,000 tons of oil - smallest of tanker accident, 2% is not small
A Very Big Accident http://www.youtube.com/watch?v=G1U-iWUPOYA
Exxon Valdez 20,000 barrels an hour 256,000 gallons afternoon 11 million gallons Biggest Tanker Accident to happen on American waters
“The Law of the Sea Treaty” Includes rules that govern airspace, subsoil, and sea beds. 158 Nations have joined this treaty since established in 1982, but the United States has failed to yet. Until we have, we will have no voting power in ratifying the future of our oceans. The United States will suffer economically due to the new issue on the future Arctic Ocean.
OVERFISHING 75% of Marine environment has been overfished. Without laws to protect the fish population from being overfished, 950 million people will lose their main source of protein. Could cause us to lose large numbers of species and/or biodiversity within the ecosystem of the ocean. Once you have affected the population of fish, you affect other species by depleting their food source and the ecosystems cycle of life.
Pollution and Littering Runoff- Septic tanks, car fuels, boats, chemicals from farms and ranches. Littering- Garbage bags, balloons, plastic, cigarette filters. OIL SPILLS!
