The Environmental Working Group (EWG) is partnering with Mika Brzezinski and her Know Your Value platform for an Earth Day Dinner, the 16th annual event at Skirball Cultural Center in California. Hilary Swank will be the special honoree, receiving the award for her role in helping pass California Senate Bill 646, which requires prenatal vitamin manufactures to disclose potentially harmful heavy metals in their products. The event will also feature leading voices in the environmental and women's health movement, including Miranda Kerr and Erin Foster, who will speak about their holistic health journey and mission behind their brand Kora Organics.
