US to ban soaps and other products containing microbeads
While it's cool and all that this has been done, it's many years after credible people started warning about the dangers of these products. The fact that manufacturers kept making this stuff with knowledge of the damage it was causing is pretty damning, and is the kind of thing that makes me mistrustful of arguments that the free market will sort things like this out. There's just no good mechanism to stop massive harm to common resources (even now, we don't have a good mechanism to stop this kind of thing, since it took years to do so, even for something as uncontroversial as this...our system barely even puts a dent in the ecological harm of fossil fuels, animal agriculture, etc.).
