The former WBA world heavy weight boxer has stepped into the ring to represent animals.
In a 2014 interview in The Independent newspaper David Haye talked about his route to veganism:
“I watched a TV documentary about how animals are farmed, killed and prepared for us to eat,” he explains, shaking his head. “I saw all those cows and pigs and realised I couldn’t be a part of it any more. It was horrible. I did some research to make sure I could still obtain enough protein to fight and, once satisfied that I could, I stopped. I’ll never go back.”
