Today’s TED Talk Greg Asner: Ecology from the air

What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail — what he calls "a very high-tech accounting system" of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.

Greg Asner’s mapping technology produces detailed, complex pictures of how humans’ activities affect our ecosystems.
