Billions will be intentionally killed by those who see the problem and the possible scenarios and decide to take control of the unavoidable die-off before chaos overwhelms and anarchy takes over.Systemic collapse is unacceptable and there will be a planned die-off.
I stand by my guess that the current cooling cycle will cause food prices to increase 4 fold in 2 or 3 years which will trigger protests,panic and riots around the globe and that will put a controlled die-off plan into action.
5 years from now big changes will have occurred and the population reduced by 500 million or more from the first planned reduction with more and greater reductions to follow.
The transition to a sustainable economy will continue even if it seems impossible to achieve.Less and less people will try to do less with less.Nuclear power will make a come back.Electric vehicles will replace internal combustion vehicles.More people will grow food at home.
