I don't feel it's properly engaging in good faith to say that I don't care. I don't specifically care, in the "feeling shame" sense that the GP had mentioned. As I pointed out, we all have a limited number of things we can realistically care about.

The fact that I happen to care about other things more than this specific flavor of global catastrophe is morally OK.

The way I see it, "from each according to their ability" is the right approach here. If you can afford 30% less flying, red meat etc, then it's your duty to do it. You don't need to make your cat go vegan; just... do what you can, even if imperfectly.

Shame is not necessary, but callous indifference is not acceptable. There is a middle ground where you treat it like a habit to improve, like a step count.
