> Biology is non-toxic Except for the toxic organisms (poison frogs, newts, fish, etc.). The best you can say on this line of thinking is that biology is biodegradable, except even that isn't true. Modern diatoms don't biodegrade - they mostly turn to sediment at the bottom of the oceans. Further, coal is mostly made of what used to be woody (lignin-containing) plants that couldn't be biodegraded when lignin first evolved[1]. The unique aspect of modern industry that makes it not sustainable is its scale and speed. The solution might involve industrially creating organisms with a similar scale and speed (like ones that can metabolize plastic). 1 https://en.wikipedia.org/wiki/Coal#Formation https://en.wikipedia.org/wiki/Coal#Formation
