I imagine in 100 years we will be basically swimming in a sea of human-engineered enzymes.

Cool to see some development on this front though, there's a whole texas-sized garbage patch in the pacific that is mostly plastic. If humans could develop techniques to easily break down the plastic that'd be great.

I think I remember reading wax worms can eat certain types of thin plastic, like grocery bags. And they excrete antifreeze (glycol) as waste.
