Around 8 i one one thousand thousand tonnes of plastic is dumped into the world's oceans every unmarried year. This plastic is unsafe to marine life and, i time it enters the nutrient chain, ultimately unsafe to the wellness of the human race.
The Ocean Cleanup scheme believes that betwixt 1.15 too 2.41 i one one thousand thousand metric tons of that plastic inwards the oceans originates from the world's river systems. Two thirds of it from the rivers of Asia. To assistance explicate how too where plastic ends upwards inwards the world's oceans the Ocean Cleanup has released an interactive map, River Plastic Emissions to the World’s Oceans.
The map shows river systems roughly the globe. The predicted input from each river scheme is shown at the coast using scaled circular markers. These predicted inputs are based on a model which looks at population density, waste materials management, topography, hydrography, the locations of dams too the reported concentration of plastic inwards rivers roughly the world.
You tin meet where all that plastic goes on Sailing Seas of Plastic, an interactive mapped visualization of the concentration of plastic inwards the world's oceans. According to the map at that spot are 5,250 billion pieces of plastic adrift on the seas of the world.
This point density map shows the estimated concentration of floating plastic inwards the oceans. Each point on the map represents twenty kg of floating plastic. The estimations are based on the results of 24 survey expeditions (2007-2013) too on air current too sea drift models.
If yous desire yous tin too overlay the sailing tracks of the 24 survey expeditions on travel on of the point map.
