The number of tires in this photo: 556, 751. Well, not really. But this beautiful image was created by TED Prize winner Edward Burtynsky, who in 2005 wished that his artwork would spark a global conversation about sustainability. Photo: Edward Burtynsky

A few numbers to keep in mind: 3, 31, and 1 million. That’s because nominations for the 2016 TED Prize are being accepted through the end of the day on March 31, 2015. You have until then to nominate a mentor, a co-worker or a visionary leader whose work you admire from afar for this prestigious prize, which brings with it $1 million for a wish to inspire the world.
