We are unlikely to cut back on resource overconsumption, it is more likely to be imposed by depletion.  Entropy is not a good idea, it's the law.

Unfortunately, overpopulation doesn't have any easy solution, not a pleasant approach, nor a violent path, or anything else.  World population increases by roughly a Eugene - Springfield every day (births minus deaths equals increase).

The 1972 study "Limits to Growth" conclusions were mostly accurate, which is not a happy prediction for our future.

Fracking, breeder reactors, mining the oceans - these and other desperate efforts are part of the mindset that created our overshoot, and not physically capable of sustaining exponential growth of consumption.  We haven't even chosen to use "renewable" resources at the rate they can be renewed (soil, fresh water, fish, trees), we use them faster than that.

There are lots of smart people in denial about finite resources.  I hope future generations learn from our mistakes.
