The 2015 Global Citizen Festival was over a week ago, yet I still can’t help but gush over one of my favorite moments of the evening.

U.S. Vice President Joe Biden took the stage as a fierce advocate for America’s leadership role in global development and called upon global citizens to be a light in the world against injustice.

The festival highlighted issues ranging from extreme poverty, climate change, and women’s and girls’ rights. Biden reminded us those issues are “distinct, yet incredibly intertwined by a simple universal truth -- that everyone in the world is entitled to live with dignity. So whenever or wherever dignity is denied, we are called to care.”

Particularly, women and girls who continue to represent the majority of the world’s poor. 70% of the 1 billion poorest people are female.

Biden finished his speech with a powerful reminder of why our work as global citizens is so important.

“No time in history has so much power been available to make such a difference for so many people. We can do this, you can do this, we can finish this job. We must!”

As Biden points out-- we are not a generation of bystanders, but one that is optimistic about achieving the Global Goals and challenging injustice. I mean, let’s talk about how over the last three months, global citizens took more than 1.5 million campaign actions before the Festival to urge world leaders to attend and make commitments for change. That is pretty powerful.

Each one of us is an agent of change. We all must continue to fight injustice and do our part to end extreme poverty!

As Biden also said, “It has never been harder to hide injustice.” No longer can the hardship of others be brushed aside. Every human is fundamentally connected and every human deserves a chance at a fulfilling life.
