In Photos: Women's Marches on All Seven Continents Demand 'A Better Future'

The second day of the Trump administration has seen an unprecedented wave of protests swell across the globe, as the Women's March on Washington and its sister marches on all continents—yes, including Antarctica—fight back against the U.S. president's frightening rhetoric.

Organizers' informal tally now puts the total number of march participants at a stunning 2.5 million around the world. And with an estimated 500,000 marchers on the National Mall in Washington, D.C., the Women's March is now the largest inaugural protest in U.S. history.

Participants and journalists are capturing the international upswell of protest:

On social media, march participants are also using the hashtag #WhyIMarch to talk about what compelled them to take to the streets:
