Living is challenging at the best of times under a 70% less-radiating Sun.

Around 195,000 years ago, the harsh climate conditions of the Ice Age began to deteriorate.

The world population was choked from 10,000s to just a few hundred that became modern humanity.


 It started around 195,000 years ago, when the Ice Age climate began to deteriorate. An extended extra-deep glaciation stage began. This stage is referred to in archeology as the Marine Isotope Stage 6, or MIS6 for short.


While most of Africa became a desert at this stage and thereby became un-survivable, a small group of people who had lived at the southern tip of Africa, had evidently survived, since modern humanity is their offspring. The small group had survived in caves at a place termed Pinnacle Point. They survived, living of the sea. A warm ocean current from the more tropical northern Atlantic would have brought enough warms to the region for precipitation to occur and also some sparse vegetation to grow. A few hundred people may have lived in this region as the result of the up-lifted climate. They were the sole survivors of tens of thousands who were known to have lived in earlier times, who perished for the lack of resources that their primitive cultures had been unable to supply, in spite of the growing intelligence of humanity.


Population-collapse events of this type where the world population falls back to minuscule levels in the shadow of collapsing climates, are referred to in archeology as Population Bottleneck events. We are facing another population bottleneck of gigantic proportions in the near future. People need food and water to live. Without them they die. We are on the fast track of loosing both food and water. A sharp down-ramping of the solar activity has begun. The Earth is getting colder and drier. The climate that gave us the power to support us as a seven billion world population, is collapsing fast, globally. And as the climate collapses, the food supply collapses with it, and with it the population density collapses.


In this regard, the people at Pinnacle Point had an advantage over us. They had lived in the one area in which the natural environment was rich enough to support their existence under the worst possible circumstances. They had available to them, what we won't have in the near future, which we have the power to create for us, but refuse to do so.


For freshwater, the people at Pinnacle Point had probably discovered a well or spring nearby that had provided enough freshwater to support a few-hundred people. But we are seven billon people in the world now, we need a correspondingly larger well or spring than just a hold in the ground.


The equivalent of the well-spring at Pinnacle Point, would be the outflow of the Amazon and Congo Rivers, and so on, on the world-scale, distributed globally. It would be relatively easy, on this basis, to supply a world of 7 billion people with freshwater during the desert conditions in glaciation times. We have the resources to build this big, worldwide - big enough to supply the needs of industries and agricultures for the whole of humanity. Why don't we do it?
