You spending time on social media or driving or eating does destroy the nature too, but you somehow justify it to yourself.
So basically if someone invented an eco-coin, that is a well-designed project fostering technologies focusing on healing the Earth (more efficient waste recycling, green energy, better air filters, new technologies for toxic and nuclear waste removal etc.), taking into account all the consequences of extreme popularity (none of the existing coins have, or they simply don't care), I'd be the first to invest in it, knowing that even if I lose, I win.
