Momentum is building around the idea of 30 x 30, the goal of protecting 30% of the Earth by 2030. But what qualifies as protected land and water? The session will explore the origins of 30 x 30 as an interim goal in the call for setting aside half of the planet for nature. The panelists, representing a broad geographic diversity in the US, will make the case that rewilding and biodiversity preservation must be at the heart of these initiatives. The session will address the welcome trend of increased attention to climate issues, but point to the need to address the extinction crisis as well. The overall goal is a spirited conversation on how the American land trust movement can advance progress on 30 x 30’s scientific underpinnings through bold action, pressing for both landscape-scale land protection and adequate safeguards to preserve native flora, fauna, and the planet.
