When Will Greens Move on to the Next Cause?

Some time ago, a mischievous person who works in the environmental/science communication sphere brought something to my attention: Laurie David, the producer of Al Gore's An Inconvenient Truth documentary, apparently became bored with global warming activism and moved on to a new cause. Nobody says that green activists should remain tethered to one particular issue. So who knows, maybe it's better that people don't turn into one-note drones. (We have enough of them, right?) But I do wonder if there will soon come a point in time when greens and environmental journalists move on to the next big environmental issue of the day. History shows this will of course happen. In my latest post at the Yale Forum on Climate Change & the Media, I discuss the last headline-grabbing green cause and the dismay by some environmentalists that it has now gotten elbowed off center stage by global warming. In my post, I suggest that the climate cause may soon suffer the safe fate. Have a read and tell me what you think.
