Beyoncé delivers a call for action in the black-and-white promo for World Humanitarian Day. The 30-year-old singer has teamed up with the United Nations and humanitarian aid organizations to launch a global campaign to celebrate humanitarian work and encourage people worldwide to get involved by helping others. Sporting braids, she delivers a powerful message in the viral clip. “On August 19. It’s high time we rise together,” says B. “Do one thing for a human being. Nothing is too small. … Make your mark and say I was here.” Beyoncé will shoot a video for “I Was Here,” the Diane Warren-penned ballad off her 2011 album 4, in front of a live audience at the UN General Assembly Hall in New York. It will be released globally on August 19.
