(Newser) – Airlifting polar bears to the Antarctic? Luring man-eating tigers out from a forest in Bangladesh? Such ideas are in the air, as biologists debate whether to move embattled species to areas less warmed by CO2. But critics say that "cowboy environmentalists" are flouting the rules—and endangering cooler habitats—by talking species relocation. 

“We need to have the conversation now, because it will probably take a decade to reach some consensus," one biologist told Der Spiegel. "It's going to be a train wreck if we wait for species to start going extinct." And there isn't much time: A Nature study has warned that two in three species will have to relocate by 2050 to survive.
