In an interview with HuffPost Live at Davos on Wednesday, Aron Cramer, president and CEO of Business for Social Responsibility, said he thinks "income inequality and climate change are actually very directly linked."

Cramer said business plays a "crucial role" in helping with those problems, saying "the great project... of the 21st century is trying to bring prosperity to a planet with nine billion people within the boundaries of the world's natural resources."

Cramer said climate change goes beyond individuals because it "is such a big topic."

"You have to make it very real for the average person," Cramer said.
