Retailers like Walmart derive the bulk of their sales from products that ultimately originate in nature. That means they have a stake in reversing the course of biodiversity loss.

"The business community has woken up and taken notice of this," Kathleen McLaughlin, Walmart's executive VP and chief sustainability officer, says "Time for nature: Turning biodiversity risk into opportunity," a livestream conversation hosted by GZERO in partnership with Suntory.

As a result, Walmart is doing its part by engaging with its suppliers on biodiversity protection. It's the only way, she adds, to "protect, restore, and better manage 50 million acres of land and a million square miles of ocean" where the company indirectly sources raw materials for its products.
