Bird's-eye view on World Environment Day

For World Environment Day today we're in northeastern Costa Rica, a nature lover's paradise. The UN established World Environment Day in 1974 to encourage awareness and action for the protection of the environment. It begins with research, which is exactly what happens in this pristine corner of the planet. The misty canopy of forest pictured here is part of La Selva Biological Station, an internationally renowned center for tropical forest research that's associated with universities and research institutions in the United States, Costa Rica, and Puerto Rico.
