I have seen recently a very interesting and unique article on Earth Witness that explain how the
Savannahs and Polar Bears are interconnected, and I thought it might be interesting to share it.
Some days later, a further thought hit me. Some of you may remember that, in my posting about my first two days on the road, I referred in passing to “…biologist E. O. Wilson’s comment that humans try to recreate the African savannah where their distant ancestors evolved, with its open grasslands and scattered trees; if the land we’re on doesn’t already look like the savannah, we remake it to look that way, regardless of the stresses this puts on the natural ecosystem.”
The point is elaborated bit later on
The basic principle is not unique to humans. It is true of all species that (in the words of Orians and Heerwagen) “if a creature gets into the right place, everything else is likely to be easier.” So every creature is always looking for the ideal place to be — the perfect habitat. Polar bears look for sea ice, hedgehogs for hedges, and humans for savannah landscapes like the ones our ancient ancestors lived in.
