Six key lifestyle changes can help avert the climate crisis

From The Guardian opinion - Elizabeth Cripps

'Reasons for apathy' #7: “I've got enough to do already!”

"I get this. I really do. But climate justice isn’t some esoteric goal. It’s about living in a way that doesn’t kill people: doesn’t drown them, burn their homes or give them malaria. So how much money or time or emotional effort should each of us put in for this basic collective morality? I don’t have a final answer because the ethical debate is continuing. But I have an answer that will do for now, for those living comfortably in rich countries. However much we should do to avert this tragedy, it’s more than most of us do now."
