In today’s globalized world, humans and nature are inextricably linked. The coupled human and natural systems (CHANS) framework provides a lens with which to understand such complex interactions.

One of the central components of the CHANS framework involves examining feedbacks among human and natural systems, which form when effects from one system on another system feed back to affect the first system.

Scientists are certain: We’re entering a mass extinction that threatens humanity’s existence.

Paul Ehrlich, CHANS-Net member and senior fellow at the Stanford Woods Institute for the Environment, and his coauthors call for fast action to conserve threatened species, populations, and habitat, but warn that the window of opportunity is rapidly closing.

"[The study] shows without any significant doubt that we are now entering the sixth great mass extinction event," said Ehrlich, professor of population studies in biology.

The stereotypical trappings of urban living -- fine restaurants, boutique shopping, amazing people-watching – need to accommodate one more city dweller: wildlife.

Cities are traditionally seen as places for people, but many species of wildlife thrive in urban areas. Interactions between humans and wildlife happen more often in urban areas than any other place on Earth. These interactions affect human health, safety and welfare, in both positive and negative ways.
