World Vegan Day is observed on 1 November, 2015, with veganism being celebrated the entire month. Vegan Day was first observed on 1 November, 1994, as a way of commemorating the 50th anniversary of the UK Vegan Society. Along with celebrating the start of the Vegan Society, Vegan Day is also an opportunity to promote the benefits of a vegan diet and veganism in general.
A vegan, as we know, is a strict vegetarian who does not even eat or wear any animal products, including milk, honey, leather or wool.

"I personally chose to go vegan because I educated myself on factory farming and cruelty to animals, and I suddenly realised that what was on my plate were living things, with feelings. And I just couldn't disconnect myself from it any longer. I read books like Diet for a New America and saw documentaries like "Earthlings" and "Meet Your Meat", and it became an easy choice for me," she wrote.

Voted as PETA's sexiest vegetarian in 2014, she tweeted: "I love animals more than I love most people, not kidding.
