Half the solution

The US is planning to list polar bears as a threatened species because of habitat shrinkage caused by climate change. This is good - with the ice they rely on disappearing, the bears will need the help - but at the same time it is also only half the solution. If they want the polar bear to survive as anything other than a sad zoo exhibit, then it is also necessary to tackle the problem at its cause, by taking action on climate change, rather than simply relying on a metaphorical ambulance at the bottom of the ecological cliff.
