Everything is Connected

Every species plays a crucial role in our natural world. But when humans tinker with the equation, a chain reaction can cause entire ecosystems to break down. In this hour, TED speakers explain how everything is connected in nature, and offer some bold ideas about how we can restore the delicate balance and bring disappearing ecosystems back. Journalist George Monbiot wants us to "rewild" — allowing creatures to reclaim their lost habitats. Jane Poynter lived for two years in Biosphere 2, where the connection among living things was often fragile and at risk of breaking down. Sound recordist Bernie Krause helps us hear the signs of vanishing ecosystems. And bee researcher Marla Spivak explains why bee colonies in the U.S. have been declining for decades.
