I’m sure if we compare governments and corporations with impact of individuals it’s not 50/50. Govs and corporations have much bigger chance at changing large scale factors, quite obviously. Even individual behaviour is in the hands of the governments – see France banning short flights as example.
the same could be said on the power of people above all with inflation, drought, heat waves, pollution waves, mindsets change slowly but surely, it'll become shameful to have noisy and polluting vehicles. I can see some environmental revolution in the future, environmental migrants, environment will be problem number 1, far ahead of minor things like covid. Government often follow and react.
