Celebrities have all of the money in the world, but they don't always spend it on themselves. Many of today's celebs give back to charities, to their communities and to people who are affected by major natural disasters. In fact, many celebrities have started foundations, organizations and charities of their own.

DoSomething.org compiled its "Top 20 Celebs Gone Good" list, which includes today's most popular pop stars, actors and professional athletes. Most of the celebrities on its list, including major pop star Taylor Swift, British boy band One Direction and NBA player Kevin Durant, are under the age of 30. The members of One Direction, who occupy the number two spot on that list, are all under the age of 25.
