Reply to comment by tjcanno in UV light from the sun slowly breaks down plastics on the ocean’s surfaces: researchers calculate that about two percent of visibly floating plastic may disappear from the ocean surface in this way each year by giuliomagnifico

... do you really need a 55 page scientific study that you'll never read to logically explain that UV light doesn't make plastic magically vanish?

Or uh.... Can we just assume within reason that plastic just doesn't disappear because the weather was good, and rather UV light makes plastic brittle, causing it to break down into micro plastics?

You totally misinterpret my question. Do you have any studies to show that when the polymer breaks down in UV that the products are poisonous?

I am not questioning that UV breaks down the polymer. I have seen it firsthand.
