Vegetarian and music icon Sir Paul McCartney is backing a global effort by the Humane Society of the United States and Humane Society International. The new “Be Cruelty-Free” campaign, the largest-ever global effort to end animal testing for cosmetics worldwide, sheds light on what McCartney calls “the ugly truth” of the cosmetics industry. “If every cosmetic … had a photo on the packaging showing these animals with weeping swollen eyes and inflamed skin, I believe everyone … would go for the cruelty-free option instead,” he says. Animal testing for cosmetics is banned across the European Union, but is still legal in countries such as the United States and Canada. Supporters can sign the petition and receive updates on how to help animals on HSI’s website.
