Yeah, humans have lived fine before fossil fuels so we can do it again, right?
Just kill half of them. And let 90% of the remaining population work in the fields like slaves. Easy /s
While I agree that modern society requires significant energy inputs, there is a middle ground. For instance, if cities or the suburbs were more pedestrian friendly, walking, cycling, etc. would be a viable option meaning less use of fossil fuels by driving.
