Transcript of The Great Pacific Garbage Patch

The Great Pacific Garbage Patch The Great Pacific Garbage Patch is an aggregation of plastics that have been accumulating at a very rapid rate since the 20th century. Improper disposal of wastes by third world nations and the production of non -degradable products is creating an aquatic dump yard. What is the Great Pacific Garbage Patch? A swirling sea of plastics and debris in the North Pacific Gyre
Worlds largest landfill on water EAST PACIFIC GYRE WEST PACIFIC
GYRE WHERE ARE THE GREAT PACIFIC GARBAGE PATCHES LOCATED? ATLANTIC GYRE WHAT ARE THESE PATCHES MADE UP OF? Accumulating trash from all over the world
Pelagic Plastics
Chemical Sludge
Other Debris picked up by currents Source of Pollutants 80% land based
20% Ships
Fishnets
Pollutants from North America take 6 years to reach the gyres
A year or less for the East Coast of Asia Major Issues Photodegration
Entanglement
Toxicity
Ecosystem disturbances How it Affects Canada Political Factors ECONOMIC FACTORS Effects:
-Fishing industries
-Cost in clean ups
-Tourism losses CONCLUSION http://www.mnn.com/earth-matters/translating-uncle-sam/stories/what-is-the-great-pacific-ocean-garbage-patch Formation - spiral of ocean water formed by colliding currents A.K.A Trash super highways
- Estimated to be 7,000,000-15,000,000 square km, 0.4-8.1% of the Pacific Ocean
- TWICE the size of the USA
- Estimated to weigh 100 million tons What is being done? - Water sampling, to see how it is interacting with marine environment
- Recycling water plastics
- Production of biodegradable materials
- Educate people on proper disposal Polluted Countries - The most polluted Rivers in the world are linked to the increasing Pacific Patch
- It is a big problem because the worlds largest polluters have a more direct entrance towards the Pacific Patch. Most polluted counties include:

- India
-Indonesia
-Ethiopia
-Pakistan
-Peru -Canada is ranked last on the municipal waste generation indicator producing over 894kg per capita (Twice as much as Japan!)
- 2008, 13 million tones of waste was generated in Canada
- Japans tsunami debris are traveling towards Canada If third world countries do not implement policies towards waste disposals, the North Pacific Garbage patch will seriously effect all the countries around the world. SOUTH

– Buenos Aires, Argetina
A.k.a The Slaughter House
-1.3 million people living there Citarum River – West Java, Indonesia Buriganga River – Dhaka, Bangladesh Ganges River – Allahabad, India
-Known as one of the holiest stops in Hinduism Yamuna River – New Delhi, India
- River full of chemical suds due to 500,000,000 gallons of sewage every day. Effects:
- No specific ownership of the 7 seas
- Countries feel little obligations to deal with something that isn't theirs
- Third world countries are less willing to contribute INTRODUCTION
