From advances in predicting earthquakes and hurricanes, to amazing insights into coral reefs and supervolcanoes, to the discovery of over one hundred thousand endangered gorillas, this was a year to remember. Stunning archival footage provides a window into the front line of science as National Geographic investigates the impact that development has had on the environment and what is being done to protect our planet.
