The Pollan family - including sisters Tracy, Lori, Dana and mother Corky - discuss their highly acclaimed new book, Mostly Plants. They sit down with Tracy's husband Michael J. Fox and actress/comedian Ali Wentworth to share family stories and how to create a mostly vegetarian diet the whole family will love. The conversation was recorded on April 17, 2019 in front of a live audience at New York's 92nd Street Y.
