People that overestimate the value of their opinions, maybe.
You can vote for candidates that take climate change seriously.
You can decide to buy or lease an EV instead of an ICE one.
You can raise the bar for when you book a flight.
And so on...
The people that believe in climate change don’t understand how to solve the problem. And the people that know how to solve the problem don’t really consider it a problem worth solving at this point.
