White Falcon, White Wolf
On Canada's remote Ellesmere Island, where June is spring, July is summer and August is already autumn, the race is on for two remarkable species to raise their families. The white gyrfalcon is enormous, the largest and most powerful falcon in the world. Yet last summer, the nesting falcon pair on the island failed to raise any young. The rare Arctic wolves rely on every member of the pack to chase and bring down the prey that keep them alive. Last year was good for them and they raised three cubs. But for the wolves and the falcons, as well for as the snowy owls, musk oxen, lemmings, Arctic foxes and hares who share this fragile ecosystem with them, fortunes are always precarious.

We’ve already lost one-third of our amphibians and more are disappearing each day. Some say it’s the greatest extinction since the dinosaurs. It’s a global crisis, mobilizing scientists around the world to stem the tide — before the next frog crosses the thin green line. Click here to see the video.
