Small acts of kindness – something as simple as lending a neighbor a cup of sugar – not only bind us together, but are critical to our survival as a species. That's according to Senior Sustainability Scientist Amber Wutich, an anthropology professor and director of ASU's Center for Global Health.

"Sharing is so important, that in most cultures it has its own special vocabulary and rituals," Wutich explains in a November 2017 KEDtalk. "Sharing helps families survive, and it's a core part of people's identity that defines their place in their communities. That's why anthropologists like me have studied how humans share in cultures in every part of the world."
