In his home of Namibia, John Kasaona is working on an innovative way to protect endangered animal species: giving nearby villagers (including former poachers) responsibility for caring for the animals. And it's working.

John Kasaona is a pioneer of community-based conservation -- working with the people who use and live on fragile land to enlist them in protecting it.

Lucy Marcil is providing fiscal services to low-income families in the doctor’s waiting room.

Richard Turere, 13, grew up hating lions. In Nairobi National Park, where he lives, lions roam freely and often targeted his family’s livestock at night.

More specifically grasshoppers, but ...

Whether or not you realize it, surfers are masters of complicated physics. The science of surfing begins as soon as a board first hits the water.
