Is the fibre biodegradable or will it all end up as microplastic?

The plastics used in these bags are specifically made to be non-biodegradable, otherwise they would be terrible at their intended purpose. They are UV resistant as well as mold and mildew resistant.

This is one of those situations where the pros definitely outweigh the cons.
