We know that the fight to save species can sometimes feel impossible at times, but animals like Toughie depend on us. We've put them in these situations and we're the only ones who can get them out. We can't lose hope and we can't stop trying. #RacingExtinction Joel Sartore, Photographer Oceanic Preservation Society (OPS) | Racing Extinction | Facebook
