NP - The Great Pacific Garbage Patch

[John Bailey]

I read a great article on this a while back. There's a vortex of
plastic in the Pacific twice the size of Texas. It will never go away.

Apparently - and I didn't know this and don't know much about chem -
pretty much every bit of plastic ever manufactured still exists in
polymer form, unless it's been incinerated.

As the wiki states, "Unlike debris which biodegrades, photodegraded
plastic disintegrates into ever smaller pieces while remaining a
polymer. This process continues down to the molecular level."
