I am in completely agreement with this sentiment, but actually getting the majority of the planet to pull along the same rope is a tall order. The question is, how do we get there?
George Monbiot has his take here: https://www.theguardian.com/books/2017/sep/09/george-monbiot-how-de-we-get-out-of-this-mess
We would have to account for a certain percentage of the population wanting to take advantage, favouring self-interest ahead of community (often masquerading behind the banner of individualism), which becomes a destabilizing force.
Others are prone to seeing this behaviour, observe their relative advantage, and wonder why it is worth their effort to do the ‘right thing’ for the community. Both selfishness and altruism spread with mimicry, but in our society the former is more of a baseline and often more contagious than the latter, which generally manifests as spikes of goodwill which fades over time. The challenge thing is to encourage the spread of the latter more so than the former and for the effect to persist, gradually pushing the equilibrium point towards one that favour community.
