You don't particularly understand nature... that's not how it works. Adaptation is a slow process, generally taking several generations and a few hundred to a few thousand years depending on the adaptation. Plastics aren't a thing that've been building up over thousands of years. The quick rate at which it's grown…

You're an idiot if you think the "new" equilibrium is going to be better than the previous one. Nature didn't develop plastic, and this plastic is a toxic pollutant to the ocean environment. Ignorance and naivety of people like you is what will lead to us ruining a entire planet b/c you think it will just balance…

So....beaver dams are made from billions of particles of plastic floating in the ocean?
Or...Mankind throwing plastic trash in the ocean is natural?
Or...what exactly?

How nature works + mankind fucking around and altering the balance = NOT the way nature works by definition.

It's worse because plastics are persistent and kill large vertebrates, in addition to disrupting the ecosystem in other. If you don't value a national park more than a garbage pit, however, you may not consider such effects "worse."

That's the whole problem. If you don't deal with them now and plan ahead, then you will not be able to deal with them in 30 years. You can't just suddenly reverse these things.
