What stake do we have in common? Naoko Ishii is all about building bridges between people and the environment (her organization is one of the main partners in a Herculean effort to restore the Amazon). As the CEO and chair of the Global Environment Facility, it’s her job is to get everyone on board with protecting and respecting the global commons (water, air, forests, biodiversity, the oceans), if only for the simple fact that the world’s economy is intimately linked to the wellness of Earth. Ishii opened TEDGlobal>NYC with a necessary reminder: that despite their size, these global commons have been neglected for too long, and the price is too high not to make fundamental changes in our collective behavior to save them from collapse. This current generation, she says, is the last generation that can preserve what’s left of our natural resources. If we change how eat, reduce our waste and make determined strides toward sustainable cities, there’s a chance that all hope is not lost.
