Sean Gobin served as a U.S. Marine tank commander and saw combat in Iraq and Afghanistan, but he never had a chance to process his experiences.
Things changed for Gobin when he and a war buddy raised money for disabled vets by hiking more than 2,000 miles along the Appalachian Trail. Gobin realized the hike also helped process his own experiences on the battlefield.
Today, Gobin's nonprofit, Warrior Hike, provides combat veterans with all the the equipment and supplies they need for their own long-distance hikes.

For Monique Pool, protecting the planet means protecting sloths, lots of them. She lives in Suriname, where city growth threatens these slow-moving mammals.
