Aaron Peirsol, U.S., Swimming

Not merely a champion in the water, swimmer Aaron Peirsol is also a champion for the water. Peirsol has partnered with Oceana on a Race for the Oceans campaign, which encourages swimmers and swim fans to “dive into ocean conservation.” Just two weeks after Peirsol set a new world record in the 100-meter backstroke at the U.S. Olympic trials, he took advantage of the media spotlight and released a new PSA calling for protection of the oceans from pollution and industrial fishing.
