This is a knowledge-sharing section that is always evolving. Many of our Champions and Partners have contributed models of best practices here. San Francisco’s Department of the Environment – a global leader – has provided nearly two dozen. Cities thousands of miles apart often face similar challenges and opportunities. Los Angeles and Mumbai, for example, both seek ways to ensure that humans and big cats can co-exist in an urban region. Cities are interdependent components of the web of life, and those strands will strengthen as we learn and create together.

“Nothing so important as an ethic is ever ‘written’… It evolves in the minds of a thinking community.” – Aldo Leopold, conservationist and writer
