You may know him for his reputation as a Hollywood playboy, ladies man, and heartthrob. But what you may not know is George Clooney is one of the celebrities that give to charity the most. Clooney has helped many humanitarian causes like disaster relief, hunger, and homelessness. Even though he helps many other causes, his main focus is donating to organizations that defend the defenseless and protect those who are vulnerable. With a couple of his celebrity friends, he founded Not On Our Watch, an organization whose main aim is to “generate lifesaving humanitarian assistance and protection for the vulnerable, marginalized, and displaced.” Clooney is a big reason why many people in show business have paid attention to human rights issues in Africa.
