Of course people need to take some responsibility, but reality is most people live in a society and do as the society does. You can minimally change people with some financial intensives but the effect of that is pretty limited and its hard to implement.

You have to create a healthy system, that takes social engineering and government cooperating on a general plan. And in the US such a thing is basically not possible, even if they wanted to do it.

Ideally your transportation, agricultural, educational policies should all work together to produce healthy population. But this simply isn't the case.

But it will not 'reduce pressure' in a practical way, because such changes purely private or public take decades to work themselves threw the population.
