Gabriela Burian, senior director of sustainable food systems at Bayer, says that hunger is an issue that the company is trying to combat.

"Our goal is to make sure we empower especially farmers that are very small across the world and farmers that don't have access to technology or to information," Burian says.

Jill Kolling, vice president of global sustainability at Cargill, says that it's important for the farmers and ranchers it works with to be able to withstand the impacts of climate change.

"Resiliency is important for our business as a whole," Kolling says. "Nourishing the world in a safe, responsible and sustainable way is now our purpose at Cargill."
