Actress Natalie Portman will be honored September 23 with an Ongoing Commitment Award at the 27th annual Environmental Media Association (EMA) awards benefit in Los Angeles. The actress first adopted a vegan diet after reading Jonathan Safran Foer’s animal-rights leaning book Eating Animals and is the producer/narrator of a new film based on the book. “I chose to adapt to a sustainable lifestyle after learning of the health risks and environmental effects that come with the mass production of animals,” Portman told Forbes. “To receive this honor is a valuable reminder to me that I am not alone in this fight.” Portman reverted to a vegetarian diet during her first pregnancy in 2011 but has hinted at returning to her vegan diet since her move to Paris—which she said is increasingly vegan-friendly. At the same EMA benefit, music mogul and vegan activist Russell Simmons will also be presented with the Mission in Music award for his promotion of a plant-based diet and work in abolishing animal cruelty.
