“We”..?
Look, I know we are all on this planet together and stuff, but the vast majority of us aren’t doing anything at all that depletes resources at a too-fast rate.
Sure, most people in developed countries have some things they could do in their daily lives to be more efficient, like being a no-scrap-left-behind sort, and if they can practically implement those changes they absolutely should, but that actually makes an insanely small difference in the grand scheme, and requires a ton of individual effort, which makes any change unlikely to stick.
Instead, let’s look at the individuals (rich people) and companies (most companies) who are using more than a reasonable share of the resources, and force us as consumers and employees to use more (throw-away culture via product design, commute especially via private transportation, dress codes, etc.) and, you know, make them stop doing that..? If we did that, and made some changes to infrastructure/zoning/public transit, individual change would necessarily follow with very little individual effort, and thus be more likely to succeed.
