The pictures are horrifying, and that is nothing compared to a 1 megaton bomb's destruction, or a 10- 1 megaton warheads in a geometric pattern blast from a MIRV.
It is awful to contemplate, but they could be the salvation of mankind. IF the slums of 500 cities were taken out with .5 mgt, enough would be killed to start a population crash and the resulting aerial particulates would temporarily cool the planet. In the aftermath, the far less people would use far less fossil fuels, aquifers, soils, and perhaps be able to live sustainably in peace. There would be a certain amount of positive evolution with the targeting of slums.
Certainly better than a man made disease which has no selectivity toward sustainability.
The natural crash will happen later, with further environmental destruction, malevolent climate change, long term depletion of aquifers and soils, and take a higher percentage of the population, with doubtful positive selectivity. The natural crash will have countless horrors, too. The sooner the better for the biosphere and survivability of the human species.
Actually, the first thing that came to mind with the pictures, was Detroit!
