Where it comes from from
About half of the runoff from land that enters the ocen comes from storm drains. They are one of the biggest issues we are facing with ocean pollution. This is why the laws have been changing to giving penalties to littering because it is all carried away eventually.
80% of ocean trash comes from land, either swept in from the coastline or carried in from rivers
Some sources of ocean pollution even start out as air pollution and is condensed into the water in waterways and in the ocean.
