    Polar Bear Listed as Threatened Species

    By Posted on 5.14.2008 7 Comments

    It's official: polar bears are in trouble. Secretary of the Interior Dirk Kempthorne has announced that he is accepting the recommendation of the U.S. Fish and Wildlife Service to list the polar bear as a "threatened" species under the Endangered Species Act. That means the bear is just one step from becoming "endangered," a category reserved for species on the brink of extinction.

    This is not any sort of revelation: Polar bears declared a threatened species , but it does raise the question: Why do we care? By some estimates, 90% of all species that once existed are now extinct and new species are always taking their place. For the species that’s going to become extinct, for whatever reason, extinction is the end of it. However, for the species that remain, is the extinction of another species good or bad. When Europeans first colonized North America, there was an estimated five (5) billion Passenger Pigeons alive and well in North America. In 1914, they were extinct. Passenger Pigeons didn’t live in little groups, but huge flocks that required extraordinary quantities of hardwood forests for them to feed, breed and survive. Deforestation to build homes, create farmland and over hunting for cheap food decimated their population. The westward drive to grow the United States in the 1800s and early 1900s was incompatible with the needs of the Passenger Pigeon and they literally could not survive in the new North America being carved out by the U.S. economy. The interesting thing about the Passenger Pigeon was the impact its extinction had on another species—man. That impact was essentially none. Man continued to find ways to feed himself through agriculture and other technologies and the United States and its citizens continued to prosper from the early 20th century till today. Whether or not Polar Bears become extinct because of Global Climate Change or other reasons, we need to address the larger question of: Do we care and why? One of the ways a nation, its citizens and the global community can answer that question is addressed by John A. Warden III in Thinking Strategically About Global Climate Change. He asks some interesting biodiversity questions in his post to include How Many Species Is the Right Number and Which Ones? Strategy without Tactics is the slowest route to victory. Tactics without Strategy is the noise before the defeat.--Sun Tzu
