Yes, everyone doing their part and looking at what they drive, how they power their home, how they eat, etc, will help.
But can I just suggest, respectfully, that saying that “everyone” does something — e.g., the “left” refuses to make changes or demands government action — is not accurate or helpful.
Of course, there are people who represent political parties with platforms and positions, but tens of millions of people that vote one way or the other are not monolithic or uniform (and that includes me — i’m not with a party, i’m a strategy consultant and writer).
But your concern is even more odd in this instance, because this article says nothing about policy prescriptions or suggestions for what to do about the problem. This one is about different kinds of denial that get in the way of action. Discussing what combination of policy, economic incentives, markets, competition, and so on, to use to tackle the problem is another debate entirely — and my larger point here is that we should be having THAT debate, not one about (a) if there’s a problem, and (b) should we do something about it now.
