Abstract
  Debate continues to rage between enthusiasts for climate change versus
  humans as a cause of the catastrophic faunal extinctions that have
  occurred in the wake of human arrival in previously uninhabited regions of
  the world. A global pattern of human arrival to such landmasses, followed
  by faunal collapse and other ecological changes, appears without known
  exception. This strongly suggests to some investigators that a more
  interesting extinction debate lies within the realm of potential
  human-caused explanations and how climate might exacerbate human impacts.
  New observations emerging from refined dating techniques, paleoecology and
  modeling suggest that the mega-faunal collapses of the Americas and
  Australia, as well as most prehistoric island biotic losses, trace to a
  variety of human impacts, including rapid overharvesting, biological
  invasions, habitat transformation and disease. [References: 67]
