A revelatory new book by Scott D. Sampson, one of our leading dinosaur paleontologists, suggests we have much to learn about extinction, global warming and energy flow from the biological experience of the charismatic beasts that roamed the Earth more than 60 million years ago.
More than any other mammal (except of course Mr. Homo sapiens), Ursus maritimus, which translates as maritime bear, has been in the forefront of the news lately, the subject of television specials, lawsuits, congressional debates, and New York Times editorials. Why?
Richard Ellis is the author of numerous works on maritime life, including “On Thin Ice: The Changing World of the Polar Bear” (Knopf, 2009) and “Tuna: A Love Story” (Knopf, 2008). He is also at work on a definitive history of the polar bear and the continuing threat to its survival posed by global warming.
