I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't help but think, the Colorado River down at the bottom isn't that big. How did it cut a canyon so massive?

    Inside an ADORABLE Sea Otter Adoption Program!

    You really otter subscribe! http://bit.ly/iotbs_sub Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate ↓ More info and sources below ↓ Otters are more than just cute, adorable little fuzzballs, they are one of the greatest conservation success stories of all time. Sea otters are a keystone species, meaning that an entire ecosystem depends on their presence. After they were nearly hunted to extinction for their dense fur, sea urchins (the otters' favorite food) nearly destroyed the Pacific kelp forests, a habitat that hundreds of species rely on for food and shelter. Thanks to the hard work of conservation scientists at places like the Monterey Bay Aquarium, sea otter populations are on their way back. Here's the story of one orphaned sea otter pup's journey back to the wild (Whale illustrations by Nobu Tamura/CC-BY-3.0) Have an idea for an episode or an amazing science question you want answered?
