Greg Asner: Ecology from the air (2013x221)


Yayınlanma tarihi: Kas 19, 2013

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.
