The island effect isn't some natural occurrence. It's the result of a series of decisions made over decades. A recent study found that if urban development continues as it has, mountain lions could disappear in Southern California within 50 years. The demise of such an important apex predator would have a downstream effect on the entire ecosystem.
Wildlife and urban development don’t usually go well together. Roads in particular fracture the habitats of wide-ranging animals. It restricts their movements and makes it harder for them to find food or a mate. But biologists and urban planners have started working together –- crafting a plan to try to help pumas move more safely around the city. And in the process this one cat, dubbed P-22, has turned into something of a celebrity—the symbol of a movement to redesign our cities and make the built environment more friendly to animals.
