Napping grizzly bear cub, Katmai National Park and Preserve, Alaska, USA

Is it just us, or does this grizzly bear cub look like he’s hugging a tree? If we’re correct, it might be because this tree-hugger is celebrating Earth Day, a global event celebrating our planet on April 22. This bear cub lives at Katmai National Park and Preserve, an area of rich and diverse ecosystems in southern Alaska that spans four million acres and is home to the largest protected bear population in the world.
