These sisters’ greenness only increases their dreaminess. Emily’s been vegan for at least 15 years and is involved with the farm-animal protection group Farm Sanctuary. Zooey appeared in the environmental-disaster-themed but critically panned flick The Happening and helped kick off a national T-shirt recycling program last year. Both sisters regularly participate in the Humane Society’s Genesis Awards. And apparently Emily convinced former Fox Chairman Peter Ligouri to try going vegan. Badass!
