David Bornstein's How to Change the World is the first book to study a remarkable and growing group of individuals around the world--what Bornstein calls social entrepreneurs. These men and women are bringing innovative, and successful, grass-roots approaches to a wide variety of social and economic problems, from rural poverty in India to industrial pollution in the United States. Bornstein provides vivid profiles of many such individuals, looking at the personalities, strategies, and techniques they have in common. The book is an In Search of Excellence for social initiatives, intertwining personal stories, anecdotes, and analysis.
