Two talks at the TED conference this year formed, back to back, a sort of debate about the future of our planet. First, Paul Gilding gave a talk entitled “The Earth Is Full,” about how we are using up all Earth’s resources, with possibly devastating consequences. Next, X Prize creator Peter Diamandis gave a presentation entitled “Abundance,” about how we will invent innovative ways to solve the challenges that loom before us.
