A man opens a gate in the Mexico/US Border near Agua Perieta, Mexico and Douglas, Arizona. Hundreds of undocumented immigrants pass across the desert here, and dozens die every year from dehydration and exposure. The man, part of a group called "Agua Por Vida" leaves water for those attempting to cross. They do not encourage people to cross the nearly 2,000 mile border but do not believe people should die needlessly.
