Never mind a no-deal Brexit, climate change is terrifying. I can go out and buy an electric car, change my energy supply to a green tarrif, recycle like mad, stop buying plastic and new stuff. Yet it isn't even a drop in the ocean if everyone else is polluting, zofloraing, buying junk, dumping junk and basically not giving a damn. I spend a lot of time in the US and they think using "recyclable" cutlery is amazing. It's barely on the radar in China.
Terrifying.
