No need to be extreme. Fly less and maybe eat one meatless meal a week. Balance.
I'm already 2 meatless days a week (not difficult). If I stop eating -full stop- only cuts 0.7t. A short economy flight instantly puts me more than 1t over the 2.5t personal emissions target, and that's just the 2030 target, never mind 2050 target. Climate = Emissions per head x population #population #vegetation #vegan #climate
