If you ask me, I'd say what we most urgently need to do is *less*.
Less of almost everything.
Less work, less consumerism, less travel, less buying, less waste, less stress, less pollution.
'Slowing down is the Revolution.'
It wouldn't be a solution for everything but it would be a good start.
And then #degrowth and #ecosocialism or something, I don't know. There's a lot of smarter people than me thinking about that.
Perhaps that's why no one is asking me. 🤷
