Saving Biological Diversity

July 2nd 2009 18:27
The conservation movement in North America emerged in part due to the shock of the extinction of the passenger pigeon and the near extinction of the American bison, species that had once been considered too numerous to be depleted. By the 1960s, a broad consensus emerged in the United States that species should not be driven to extinction by human activity. Since then, however, the Endangered Species Act and major programs to restore endangered and threatened species have become controversial.
Private property rights advocates claim that endangered species protection hampers economic activity and land development to an unreasonable extent. At the same time some conservationists are concerned that too much money and effort are devoted to endangered species, diverting efforts from protection of entire ecosystems that support numerous species. They argue that given the limited resources available, preventing common species from becoming rare is the most effective long-term strategy. Defenders of endangered species programs claim that protecting endangered species usually entails protecting entire ecosystems, and endangered species can serve as effective symbols to rally support for ecosystem protection.
