History/Plastics
Context/Premise: History
• The Patch is a gyre of marine litter in the central North Pacific that gradually formed as a result of marine pollution gathered by oceanic currents off North America and Japan.
• Currents carry debris from the west coast of North America to the gyre in about five years, and debris from the east coast of Asia in a year or less.
• Wind-driven surface currents gradually move floating debris toward the center, trapping it in the patch.
• The Patch contains high concentrations of disintegrated plastics, chemical sludge, and other debris.
• An estimated 80% of the garbage comes from land-based sources, and 20% from ships.
Plastic:
• Each person produces 1500 pounds of garbage a year, 10% will end up in the ocean. The ocean is the last stop for all littered waste.
• Garbage biodegrades, but plastics polymers do not. Photodegradation breaks down plastics into smaller pieces, but these pieces will never go away.
• Plastics contain Bisphenol A, which leaks out when immersed in water. Bisphenol A leads to multiple health risks including infertility.
• Plastics can be recycled.

OUTLINE
So I started working on the outline. It still needs a lot of work. Right now it's mostly wikipedia.
But I was thinking of this:
1. Opening - A story on the discovery of the patch.
2. Context - The history and development of the patch.
3. Options - Not too sure where we want to go. Since this is the meat of our presentation, I think we should discuss together further.
4. Conclusion - Cleanup initiatives and a sense of hope and progress.
Let me know what we think.
Why you should know about the great pacific garbage patch
Opening:
The existence of the Great Pacific Garbage Patch was predicted in a 1988 paper published by the National Oceanic and Atmospheric Administration (NOAA) of the United States. The prediction was based on results obtained by several Alaska-based researchers between 1985 and 1988 that measured neustonic plastic in the North Pacific Ocean. This research found high concentrations of marine debris accumulating in regions governed by particular patterns of ocean currents. Extrapolating from findings in the Sea of Japan, the researchers hypothesized that similar conditions would occur in other parts of the Pacific where prevailing currents were favorable to the creation of relatively stable waters. They specifically indicated the North Pacific Gyre.
Context/Premise: History
The Great Pacific Garbage Patch is a gyre of marine litter in the central North Pacific Ocean. Media claims that the patch is larger than the size of Texas. The Patch is characterized by exceptionally high concentrations of pelagic plastics, chemical sludge, and other debris that have been trapped by the currents of the North Pacific Gyre. The patch is not easily visible because it consists of very small pieces, almost invisible to the naked eye; most of its contents are suspended beneath the surface of the ocean.

Summary:
Conclusion:
There are many various cleanup initiatives implementing solutions:
1. The Environmental Cleanup Coalition collaborates with other groups to identify methods to safely remove plastic and persistent organic pollutants from the oceans.
2. The JUNK raft project highlights the plastic in the patch, organized by the Algalita Marine Research Foundation.
3. Project Kaisei initiated two project vessels, the New Horizon and the Kaisei, embarked on a voyage to research the patch and determine the feasibility of commercial scale collection and recycling.
4. The SEAPLEX expedition, a group of researchers from Scripps Institution of Oceanography, spent 19 days on the ocean researching the patch. They took samples and spread awareness; two steps essential to the cleaning-up process.
5. The Plastiki is a boat-building project by David Mayer de Rothschild hoping to highlight cleanup issues and sustainable plastic technologies.

Opening: Goal presentation will achieveMarch 9th Tuesday Night Class
The Great Garbage Patch is located between Hawaii and San Francisco in the Pacific ocean. It is roughly the size of Texas and contains 3.5 million tons of trash.
The garbage patch formed gradually as a result of marine pollution gathered by ocean currents. The rotational pattern draws in waste material from across the North Pacific Ocean and coastal waters off North America and Japan. Currents carry debris from the west coast of North America to the garbage patch in about five years, and debris from the east coast of Asia in a year or less. It is estimated that 80% of garbage comes from land-based sources with the remaining 20% from ships. (A 3,000 passenger cruise ship produces on average over eight tons of solid waste weekly)
Much of our waste today is comprised of plastic that does not biodegrade. Shoes, toys, bags, pacifiers, wrappers and plastic bottles are some of the items that can be found in this ‘accidental dump.’ Pollutants range in size from abandoned fishing nets to micro-pellets used in cleaners. These long-lasting plastics end up in the stomachs of marine birds and animals. Many have died from starvation and dehydration as a result of this. Fish are “ingesting plastic particles laced with toxic chemicals at such a rate that soon they will no longer be safe to eat.”
There is a video on this website that helped me understand the Great Garbage Patch further. http://www.greatgarbagepatch.org/
