The Tragedy of the Commons
Transcript of The Tragedy of the Commons
Over Fishing. Possible Solutions 50,000 barrels of oil are dumped into the sea every day.
About 20,000 tons of fish are taken out of their environment
every day. The Clean Water Act
( http://www.epa.gov/lawsregs/laws/cwa.html )
Federal Government programs that regulate the amount of waste that can be placed into the ocean.
Independent Environmental Groups Beach Pollution is a rapidly growing issue in the United States, and is a cause for much concern. From 2009 to 2010 increased 29% The amount of beaches that consistently exceed standards rose from 9 to 11%, to the best of our knowledge. In 2011 only 57 % reported being monitored regularly, only 45% being at least once a week.
In 2011 alone, there were 23,481 beaches closed, that is the 3rd highest for 22 years. Causes of Beach Pollution Beaches usually get closed for high levels of harmful micro-organisms in the water that are caused by sewage.
This can be caused by untreated storm-water run-off, boat waste, sewage overflowing, or malfunctioning sewage systems.
Other pollutants include trash, pet wastes, motor oil, pesticides, fertilizer, etc...
70% of closings in 2011 are from unknown sources. Effects People who swim near storm run-off are 50% more likely to get ill
This can cause fevers, nausea, and other flu like symptoms.
This can also lead to dysentery, cholera, typhoid fever, and other unpleasantries
This can harm local wildlife,
It also harms the economy, the average beach-goer is worth 35$! Solutions There are many possible solutions to beach pollution,
Increased clean up efforts and local help
Increased awareness of the problem
Support for B.E.A.C.H (Beaches environmental assessment coastal health) who's focuses are strengthening beach standards and testings, providing faster laboratory test methods, predicting pollution, investing in health and methods research, and informing the public. There are three types of Over Fishing. Growth overfishing occurs when fish are harvested at an average size that is smaller than the size that would produce the maximum yield per recruit Ecosystem overfishing occurs when the balance of the ecosystem is altered by overfishing. Recruitment overfishing occurs when the mature adult population is depleted to a level where it no longer has the reproductive capacity to replenish itself Solutions. There are many solutions in the works for over fishing. Such as Quotas,
a limit on how much a single vessel, nation, or company can fish. This are mainly enforced through the
United Nations Convention on the Law of the Sea
