Ecology


one planet, one ecosystem

We've only begun to appreciate in the last fifty years how complex — and fragile — ecological systems are. Even more recently we've realized how interconnected the health of those ecological systems is with our social and economic systems. We used to drain swamps to claim land for development and to control pesky mosquitoes, but now we understand that wetlands are crucial for flood control and for providing habitat to countless species. We used to think the oceans and atmosphere were too big to be polluted, but we now realize that we risk setting off catastrophic and self-reinforcing changes if we strain these systems too hard.

Our deepening understanding of ecology has taught us another important lesson: healthy systems do not remain the same for years and years, but instead adapt to change over time by cultivating resilience.
