There's no debating the popularity of the #selfie.
Even NASA enlisted the frequently used social media self-portrait to honor Earth Day 2014.
The images will later be compiled into a planet-wide mosaic, which will be released by NASA in May.
Several San Francisco 49ers players gathered in the team's locker room to take part in the event.
Fullback Bruce Miller, with his left arm extended, captured the shot alongside teammates Kendall Hunter, Darryl Morris, Jewel Hampton and Marcus Lattimore.
Just like that, the 49ers wished everyone a happy Earth Day.
