Facebook founder and CEO Mark Zuckerberg says his new “personal challenge” of eating only meat from animals he has killed himself has come to fruition in a big way. The young billionaire took a bison and has even posted pictures on his Facebook page showing him cooking up bison burgers, according to Mashable.com. Fortune magazine confirmed Zuckerberg recently obtained a hunting license and killed the bison. Zuckerberg said before he took the bison, he’s dined on self-killed pork, lobster, goat, and chicken. “(People) should take responsibility and be thankful for what they eat rather than trying to ignore where it came from,” he previously wrote to Fortune magazine. Ted Nugent had previously offered some advice to Zuckerberg about his challenge. “Hunting is the pure and natural way to go grocery shopping for high protein, extraordinarily tasty and nutritious renewable wildlife, but you first have to aspire to a higher level of awareness in order to get close to the most wary and skittish beasts on the planet,” Nugent said in a press release. “My advice for Mark is to go slow, soak in the mighty spirit, and to call me.”
