Why we need to protect half the planet

New research indicates current global conservation targets, which call for preserving 17 percent of land and 10 percent of oceans, are far too low. Instead, targets should be closer to 50 percent for land and 30 percent for oceans. This will protect the diversity of life on Earth and ensure human well-being and survival. Join panelists for this critical discussion on why we need to increase conservation targets in order to save the Earth.
