The thing is that everyone alive today and in the future is footing the bill for that indifference. It's nice that you don't care, but it's not something I'd brag about.
I too don't want to be a martyr hermit who don't travel and consume just to cur my CO2 emissions in half, while someone else generates 10x of that living a full life.

At the very least don't brag about not giving a crap.
