Beyoncé aims to reach 1 billion people on one day with one message of hope with the video for “I Was Here,” dedicated to World Humanitarian Day.  The pop powerhouse 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 on August 19.  Beyoncé filmed the visuals in front of a live audience at the United Nations General Assembly Hall in New York earlier this month.

“It says, ‘I want to leave my footprints in the sands of time’ and it basically is all of our dreams,” B told Anderson Cooper of the Diane Warren-penned ballad off her latest album 4.  “And that’s leaving our mark on the world. I feel like we all want to know that our life meant something.”

The video was helmed by production company Ridley Scott & Associates and directors Kenzo Digital and Sophie Muller (“Ring the Alarm,” “Deja Vu”).
