The Giving Pledge, the foundation created in 2010 by Bill and Melinda Gates and Warren Buffett to use their fortune to solve the world's problems, has added 14 new billionaire members.

The Pledge encourages the world's wealthiest individuals and families to give the majority of their wealth away to philanthropic causes and the foundation announced this week that 14 more individuals hailing from Australia, China, Cyprus, Monaco, Norway, Slovenia, Tanzania, and the United States, have agreed to Pledge.
