You are wrong regarding disposal of plastic. Most of developed world does not recycle its plastic, we ship it to China or Philippines, where its sorted by hand, or illegally burned and land filled. Often it is shipped there illegally by our own governments. Recently China stopped taking contaminated plastic, and much more of it now ends up in even poorer countries. Many kinds of plastic are 'unrecycleable' at all, like most plastic bags and films. Some are recyclable (like plastic bottles) but uneconomic to sort from the grades of plastic that aren't, from each-other, and from random food contamination. No country in the world has achieved good track record of recycling plastic, and it probably impossible without very tight control and discipline.

Unrecycleable plastic in single use items should be illegal.
