On the topic of what we do though, campaigning for actually effective legislation 1) actually works, and 2) has a far greater effect than trying to micro-optimize our individual lives. Optimization problems are solved by gathering data and focusing on the largest contributor, not just picking shit randomly.

Also, make no mistake, enacting a carbon tax, for example, would make all of our lives harder, we simply wouldn't be able to afford as much stuff as we do now. But it would align the market forces to find efficient, low-carbon solutions, as opposed to find efficient solutions despite carbon emissions. Trickle-down economics is bullshit when it comes to rewards, but no company (that stays in business) ever shied away from passing along operating costs. (A similar thing happened to nutrient labeling, the food industry fought tooth and nail against it because it would be a downturn in the business, but it was ratified anyway and since then options across the board got a lot healthier, because there was simply an incentive for the corpos to fix their shit to some degree where there previously wasn't. And that was just about informing consumers, not fully ) So don't make this out as if we're just pointing the blame so you can sit back and let the big companies do all the work, because that's not what this is about, it's simply about the fact that capitalism doesn't run on morals (as it is so clearly apparent in its results) so we need a little more than that to force the corpos to work along with the rest of us. Because if they don't, all our efforts will be in vain.

The point is, regulation would actually work. We tried to make climate change the individual's responsibility for decades and we're still barreling straight towards the climate apocalypse, so it's time to add some other measures too, not just try to slightly increase individual contributions and see if that solves it. Spoiler: it won't, but it's comfy to some high-ranking execs if we waste valuable quarters trying that again and again and again. And I guess it gives us a comfy delusion of control too.
