Talk is cheap, so it's easier than actions. If it was important enough to people, they'd act, even if there were some costs and inconveniences. That's the difference betwen people saying what yhey want, and their revealed preferences.
Take climate change, something I suspect we agree on. People won't take individual action, and so it's no shock that they also won't vote for a politician who will promise to force them to take action, unless they are convinced that the costs to them will be small. Also, a hot take - climate change denial is partly virtue signalling by people who'd just rather have other people solve the problem but don't want to admit that. Yeah, big oil propaganda and a hostility between creationists and scientists is also a factor.
