Addressing major environmental challenges in all their dimensions is ultimately about working at scales big enough to have a global impact. That’s the perch occupied by Carter Roberts, president and CEO of the World Wildlife Fund. His organization works to preserve the Earth’s wildest places through collaboration, community empowerment and government engagement at all levels. WWF speaks to our hearts through beautiful images and stories — and to our minds through economic analysis, land use planning and more. Success demands the agility to view complex systems from different angles, stitch together resonant narratives, and partner with stakeholders around the globe and across public and private sectors.
