...if you share my desperation and terror about this crisis, the urgent desire to do something, then limiting your personal carbon footprint should be very far from your main concern. Like, it’s great if you can bike to work, and you should keep it up (fresh air and exercise and all). But I’d say the anti-environmentalists are right that such voluntary steps are luxuries of the privileged, and will accordingly never add up to a hill of beans. Let me go further: even to conceptualize this problem in terms of personal virtue and blame seems to me like a tragic mistake, one on which the environmentalists and their opponents colluded.
I think it's a really important question, so I thought I'd post my response here.
