OP-ED: We Need Everyone to Build a More Sustainable World

Last week, I had the privilege of attending the Delhi Sustainable Development Summit, an annual event that deals with a subject that is very close to my heart.  The summit gathered together amazing people: Nobel Prize winners, thought leaders, heads of state, corporate innovators, and academicians to deal with the paramount challenges of the 21st Century all focused on three pressing dimensions of sustainability:  food, water and energy.
