I'm not particularly interested in owls but this article from the New York Times shows great images of snowy owls in their natural habitat. Many habitats will be affected by global warming and owl researcher Denver Holt explains why we should place particular focus on snowy owls: "if climate change results in habitat changes and it affects the lemmings, it will show up in the snowy owls because 90 percent of their diet is lemmings. The owls are the key to everything else."
I hardly think owls are more "key" than anything else in the circle of life but the New York Times stressed the "unscientific reason to study the snowy owl". Owls as mascots for the green movement simply because they're photogenic? Why not?
