Take this From Facebook founder Mark Zuckerberg who has vowed to only eat meat from animals he has killed himself!

Each year, the social networking mogul takes on a new personal challenge in order to build greater self-discipline and expand his interests and knowledge. In 2009, he vowed to wear a necktie each day for the entire year and last year his goal was to learn Chinese, but for this year’s challenge he wasn’t afraid to go for something quite a bit less tame. Naturally, the big reveal came via his Facebook page, with his status reading “I just killed a pig and a goat.” on May 4th! Zuckerberg has been guided in this unusual venture by a well-known Silicon Valley chef by the name of Jesse Cool. She was even there giving him pointers as he killed his first chicken, pig, and goat! After Zuck kills his prey, the dead animals are shipped to a butcher in Santa Cruz, who prepares the flesh for consumption. Mark and his girlfriend then cook the meat and eat it for dinner - he even devoured the chicken’s heart and liver!
