Finally: Al Gore goes vegan

An individual familiar with Gore’s decision, who asked not to be identified because it involved a personal matter, confirmed that Gore opted a couple of months ago to become vegan. Gore’s office did not immediately respond to a request for comment.

It is unclear why Gore, one of the nation’s most visible climate activists, has given up dairy, poultry and meat products. People usually become vegan for environmental, health or ethical reasons, or a combination of these three factors.
