The Great Pacific Garbage Patch Niki Ahmadi

What is it?  A wide range of mostly confetti sized pieces of trash floating together in a large mass in the Pacific ocean.

What does it look like?  Not easily visible  Like “confetti soup”  Size relatively unknown  Estimated at 270,000 square miles (Texas) to 16,000,000 square miles  Has a depth of 100 feet

How did it get there?  North Pacific Gyre  California Current  North Equatorial Current  Kuroshio Current  North Pacific Current

How did it get there?  Existence predicted in 1988  Has been forming since 1960’s  Takes several years to travel from North America  One year from Asia

How did it get there?  As plastic production increases the mass increases  In 1999,.02 grams per square meter  In 2005,.04 grams per square meter  Within that time period plastic production increased by double digits. Reaching 113 billion pounds.

How did it get there?  80 % of the garbage comes from the land  20 % percents from ships  A 3000 passenger Cruise-Ship creates 8 tons of garbage weekly

Effects  100 million tons of trash  The world produces 200 billion pounds of plastic each year, about 10 percent ends up in the ocean  Every square mile of ocean hosts 46,000 pieces of floating plastic  70 percent of the plastic floats to the bottom of the ocean

Effects  Marine animals mistake non- biodegradable plastic for plankton  Plastic outweighs surface zooplankton 6 to 1  Leaks toxic chemical into the ocean and into the marine life  Including :  PCB’s  DDT’s  PAH’s  All are toxic and dangerous to the immune system

Effects  Large trash can trap animals  Facilitates the spread of invasive species which can attach to the debris  Humans eat fish and are affected by hazardous toxins  The plastic debris affects at least 267 species world wide

What is being done?  No one country’s responsibility.  GPGPT (Great Pacific Garbage Patch Treaty)  No UN nation has signed to take responsibility  Trash is hard to clean up due to size  Satellites cannot detect debris

What is being done?  ECC (Environmental Cleanup Coalition)  SEAPLEX expedition  Project Kaisei  JUNK raft project organized by The Algalita Marine Research Foundation
