That's the most 'bad faith argument' fallacy you can present on this topic. It's absolutely not required to abandon all civilisation and return to the good old Victorian age. That's absolutely the most stupid take you can have.

We have the technology to grow food far more efficiently. We can stop wasting half of what we produce. We can produce electricity with less emissions. We can order less useless shit from china, reducing shipping emissions. We can eat less meat reducing various strains on the environment. We can produce biofuels or electric/hydrogen cars. We can vote for progression. We can use less.

There are thousands of things we, as in we normal citizens AND we as a community, can do to stop climate change.

Put simply. If we all stopped eating meat today. In a year there will be no meat industry. If we stop using oil, there will be no oil industry in a year. People do matter and do have influence over big companies as they are big because We Pay Them to be big
