@Elucidating maybe you should learn about how plastics are actually made before getting on the train of PLA because "no oil". We don't make oil to make plastics.

> Although crude oil is a source of raw material (feedstock) for making plastics, it is not the major source of feedstock for plastics production in the United States. Plastics are produced from natural gas, feedstocks derived from natural gas processing, and feedstocks derived from crude oil refining.

It is a free *byproduct* of refining that would otherwise have to be dealt with as industrial waste, but instead they figured out how to make it into plastic and sell it to us.

There is never going to be a plastic that is safe for the environment.
