An individual giving up their car and living in a yurt has literally zero impact on the global problem. It’s like being in a burning stadium and saying “well that person won’t toss their 4 oz drink on the fire, so why should we bother calling the fire department?” Strong concerted effort from people with social/economic/political power is pretty much the only thing that can actually move the needle in terms of biodiversity loss, global warming and all its consequences, etc. just imagine if Silicon Valley companies exerted effort similar to what they’re willing to do to subvert labor protections to change our energy infrastructure!
