Ron Garan, ISS Expedition 27/28, was profoundly moved by viewing Earth from orbit.
On returning from space, he established "Fragile Oasis", a non-profit to help make the world a better place. It highlights and "crowd-funds" world-wide efforts for food, health, energy, environment, and other domains.
He also took some amazing pictures (below)
Please visit Fragile Oasis and support good causes!
