For more than 27 years, one man made it his mission to serve up sustainability with the 75 hamburgers severed every second at McDonalds. Bob Langert led the social responsibility and sustainability efforts at the fast food giant when it first came under attack for its environmental record. Retired now, he worked on projects to reduce waste and animal cruelty, and acknowledges there is more work to be done. He gives insights into how environmentalists can work more effectively with large corporations to facilitate real change.
His new book is called The Battle to Do Good: Inside McDonald's Sustainability Journey.
