2 weeks after people, The Great Pacific Garbage Patch is an area in the Pacific Ocean, halfway between San Francisco and Hawaii, which contains 3.5 million tons of plastic garbage. It is twice the size of Texas. Storm drains now wash the litter that has gone uncollected in Los Angeles into the Pacific Ocean which increases the size of the Great Pacific Garbage Patch.

The Great Pacific Garbage Patch is now a poisonous stew of toxins and it continues to poison ocean life. However much of it is eaten by seagulls so that not all sea life will be poisoned
