I'm not so worried about humans maliciously trying to destroy the world. There are few who would do so intentionally.
Far more worrying is when people do what is easiest for them, regardless of the cost to their neighbour.
A mask collects particles, including the COVID-19 virus. Please can we work together to pick up the masks from the street?
Worms will eat the masks. Bats will eat the worms. And the bats will give COVID back to us.
We're not responsible for world-scale Epic issues: plastic in the ocean, climate change, pandemics. We are fully responsible for the Issues we see. Please, let's clean the streets while we cycle/walk dogs/skateboard and the butterfly effect will help to fix the bigger problems too :)
