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.
