It will biodegrade just laying around anywhere, with not even a backyard composter, 1000x sooner than all the normal plastics.

Some other things can even go faster and easier, but you can use pla without feeling guilty of anything.

It doesn't do the world any good to make anyone wary of such a huge improvement.

1000x sooner is still a really long time, I've seen numbers like 80 years thrown around. And that's with normal PLA, not PLA+ and other popular modifications that may have very different properties. You are right that it's significantly better than ABS for example, but "less environmentally hostile" and "environmentally friendly" are not the same and imho a lot of the info out there is simply misleading in that regard.

It doesn't do the world any good to lie about the degree to which things help either! We can be realistic about our need to properly dispose of PLA in an industrial composter, and still accept that it's a massive improvement over other plastics
