Thanks for this article on such an important topic. Really, there is probably nothing more important. Which makes how we communicate about it all the more critical.
On any given day, the average person makes a myriad of decisions. The "moms and dads" depicted in the drive-thru with carloads of kids are doing logistical gymnastics. I know, I have three kids. But having kids doesn't matter -- we're all busy dealing with our busy lives.
I've often mused that to live a low/no-impact life (remember the documentary No Impact Man?) would be a full-time job. Just being vegetarian and running a small homestead / garden in addition to work and childrearing keeps me running 24/7.
People have to pick and choose where they make their efforts. Shaming where they falter, I've found, or virtue signaling, never works, and is often counterproductive. Plus, there's a myth of hyperagency these days that, if anything, is sold to us by the corporations themselves.
Because where in your article, for instance, are the fast food companies themselves held accountable? You mention how the fossil fuel industry stymied the development of the electric car -- the the industry's political lackeys -- it's the same here. The fossil fuel industry and big agribusiness are at fault. People were fine before fast food and will be fine after its gone. Consumer demand does bear some responsibility but climate change is too important an issue to foist solely on the consumer and finger wag until it goes away.
Eat the rich, topple the corporations. Then maybe we'll get somewhere.
