Earth has always been a place of constant flux, but the change accelerating around us today is far from natural. Plant and animal species are vanishing at a rate unmatched since the age of the dinosaurs—in many cases before we can even name them.

The Academy’s programs of research, education, and public engagement are cause for optimism in urgent times, helping people of all ages to hone science-literate brains and the passion to protect biodiversity. In our day-to-day work and overarching goals, we're guided by a mission statement as profound as it is simple: to Explore, Explain, and Sustain life on Earth.
