What can be done? Try a few of these things, Old guy.

Drive a smaller car, that will do better gas milage. Try and do fewer miles in it, by combining trips and such like.

Insulate you house well, and get used to wearing a sweater indoors in the winter.

There are lots of others, but I don't know your circumstances. If you live in cabin in rural Alaska, it will be well insulated already, and you do need a four wheel drive out there.

It's not a question of going back to the stone age, it's simply producing electricity , and running cars in ways that don't produce Carbon dioxide. It wil take decades to get to that stage, so in the meantime, use ways that produce less.
