Oscar-winning American actor, singer, songwriter and director. Leto was front-man and co-founder of rock band 30 Seconds to Mars and has starred in the films Fight Club, Dallas Buyers Club, Requiem for a Dream and American Psycho.
Leto became vegetarian when he was a teenager and a few years later, after learning about the presence of pus in dairy products, switched to a vegan lifestyle. He has frequently been praised for his youthful looks, which he has attributed to his healthy vegan diet and love of hiking. He made a trip to South Africa to learn about rhino poaching and stated that humans "have an important responsibility to protect and shepherd these fragile species and their habitats. I’m committed and passionate about doing all I can to help ensure that these endangered animals survive and will continue to encourage others to get into action as well.”
