“All plastic evermade still exists”?

Nope!

That is Grenfell Tower burning courtesy of Wikipedia. What is important is the pannelling that was so disasterous was Aluminium coated with a polyethylene core (i.e. plastic core). The image therefore includes plastic burning. Plastic that burns is no longer in existence. We burn plastic regularly! Yes this is a cause of green house gases and I would never trumpet it as a solution but we need to note that we do destroy plastic as well as create it.

When you are going to make claims about plastic please make genuine ones, not ones that are so easy to disprove.
