That doesn't mean it can't be a pollutant. To take a simple example, fertilisers are biodegradable and yet run off + eutrophication is incredibly ecologically damaging.
- jillesvangurp 8y agoSure, but why would you assume it is? Also, you'd need a lot of this stuff to do any damage even if it was that much of a pollutant.

- jillesvangurp 8y agoAt less than a gram per lens, there's only so much damage those are going to do. I looked it up, we're talking about 23 tons worth of lenses for the US. A lot, but it pales in comparison to other stuff we do to the environment. Like traditional batteries for example, which we're talking about replacing with something bio degradable.
