We could accomplish all the results of a Green New Deal at only a small fraction of the cost and within a very short period of time.
There are several relatively inexpensive means. EMP bomb, bio weapons, chemical weapons. Even an intense regional nuclear exchange (India v Pakistan) would have planetary wide effects if there was enough nuclear fallout.
A green new deal would mean a 19th century lifestyle for most of what’s left of the public. The Georgia guidestones prophecy could be realized. The elites would retain a very advanced lifestyle.
That’s it! An EMP. No need for government mandates, burdensome taxes, abortions, population control. Anything with electronics gets fried, and we all have to learn to live off the land. About 10% - 15% of the population would survive the lack of food, water and electricity. Great way to cut CO2 emissions.
I just wish it would detonate over blue states only. That is, right after I leave California.
Funny, though. The cows are better suited for an EMP and would outlive the humans, generating uncontrolled methane emissions.
