Not Our Fault

A recent study has concluded that the woolly mammoth died out due to declining pasture land, rather than being hunted to extinction by early humans as some scientists have speculated.

Interestingly, climate change apparently played a role — although no one seems to be attributing that climate change to humans (yet).  During the Ice Age, there were smaller concentrations of carbon dioxide, which discouraged tree growth.  As a result, there were vast pasture lands that were perfectly suited to large grass- and plant-munching beasts like the woolly mammoth.  As the Ice Age receded, climates warmed and carbon dioxide concentrations increased, which in turn led to the development of forests that encroached on the grasslands that were crucial to the survival of the mammoths.

The study is based on computer simulations, so there will still be room for debate.  Nevertheless, it is nice to think that our ancestors were not responsible for the extinction of these striking, colossal creatures that roamed the planet at the dawn of mankind.
