  1. Why do you limit your focus of the impact of human expansion to homo Sapiens? You mention Neanderthals and Denisons in passing, but don’t consider the impact they could have had, or the impact Homo sapiens could have had on them. Also no mention of the motive for migration - such a rapid expense usually happens for a reason. Climate change perhaps? And with any migration of a species, particularly Homo sapiens, comes diseases.

  2. Also it’s a logical fallacy just to think that because one thing happens after another it happens because of it. The same thing that helped cause the extinction of mega fauna could well be what motivated Homo sapiens to migrate. And Homo sapiens weren’t the only thing hunting mega fauna. They may have contributed to or sped up their eventual decline but attributing the extinction of all mega fauna solely to Homo sapiens without any conclusive evidence at all other than the fact humans hunted them is ridiculous for someone who chains to want solid evidence. If humans had been around to hunt dinosaurs would you attribute their extinction to us too?

  3. You missed off a really obvious reason for no human burials at a time of rapid climate change and great hardship, cannibalism.

  4. Global sea levels rising by 4cm a year today would be an absolute disaster, within 100 years most of the worlds cities and much of its arable land would be flooded
