Beavers feast on new green shoots, baby bison take their first faltering steps and grizzly bear cubs emerge from dens to explore this new green world. But spring is also a perilous time. Wolves are hungrier than usual after slim winter pickings. And rising temperatures melt the vast mountain snow pack, sending a million tons of water flooding into the rivers. Only the toughest will survive.

The leatherback sea turtle is a magnificent creature that can be found in Atlantic, Pacific, and Indian Oceans. This ancient species swims faster, travels further, and dives deeper than any other reptile on the planet.
