In April 2011, about 48,000 people filled five blocks of Flora Street in the Dallas Arts District for the first Earth Day Dallas. Eight years later, more than 177,000 came to Fair Park for EarthX, the largest environmental gathering of its kind. Today EarthX is a Congress of Conferences that brings presidents, prime ministers, scientists, explorers, investors and students to Dallas every April.

X Stories collects those years: the people who took the stage, the programs that began there, and the photos, films and memories that remain.
