Musician Paul McCartney isn't shy about taking a stand for animal rights -- the vegetarian superstar has talked about his journey to a meat-free diet and supported Meatless Mondays -- and now he's speaking up for another group: the monkeys that NASA uses to predict how space travel will affect humans. According to Gigwise, the singer-songwriter says, "I believe NASA has the ingenuity to investigate the health effects of space travel without confining and experimenting on animals as was done in the old days. It would be terribly disappointing if in our zeal to explore new frontiers and to learn about the fascinating universe where we live we began to regress in our treatment of the animals with whom we share this planet."

Model and "Alter Eco" host Angela Lindvall spoke to EcoStiletto about the challenges of balancing her professional life -- and representing brands that don't always make sustainability a top priority -- with her personal green ethics and morals. Though she says it's been a difficult task, her new roles as the face of DNKY Pure and Biotherm's new organic products and as a member of the NRDC's Clean by Design Initiative mean that both of her passions are starting to come together. "It's super exciting to take the message of beauty and skin into a more holistic approach -- from the inside out," she says. "It's much more than skin deep. Women feel so much stress juggling between their careers and their families. The stress that we have compared to our grandmothers is just insane."
