Personally I want to reduce road traffic in favor of electric public transit, heavily reduce meat consumption, ban fast fashion and all but eliminate single use plastics, completely stop fossil fuel extraction and use.
And I think the way forward is for the globally privileged elite (that's primarily us in Europe and the US) to lead by example and use the greater resources available to us to make a difference first, improve our spotty record instead of leaning back and just dictating to others what we think they should do. Historically, we've already done that more than plenty already.
