While some greenies buy vegan clothes and footwear that are made from non-animal materials, Natalie Portman actually designs them, too. The actress lent her name and voice to the Animal Planet documentary Saving a Species: Gorillas on the Brink, which highlighted the threats to the animals’ rainforest habitat. Portman has also been active in groups like Global Green USA, an organization that tackles environmental issues on an international scale.
