The interview, which is featured in the Winter 2015 World Wildlife Magazine, covered a broad range of topics including Roberts's favorite animals, his family and what people can do to help the environment.
Mayer told Roberts about the moment when she first realized she was a nature lover and about a company she started with a friend that sells environmentally friendly bath products.
Last year, Mayer prepared a speech for her sixth grade public speaking project about endangered animals. The speech was passed on to Roberts through a family friend.
Impressed by her speech, he asked her to visit WWF headquarters in Washington D.C. and interview him for the organization’s magazine.
