This series tells the dramatic stories of 14 daring social entrepreneurs who are undaunted by the chronic challenges of poverty, illness, unemployment, violence, and ignorance they see in the world around them. With a revolutionary passion for transforming society, brilliant insights to achieve fundamental change, and an unstoppable will to overcome obstacles that preserve the status quo, these individuals tackle the most intractable social problems and achieve extraordinary success. They are called social entrepreneurs because they have the kind of vision, leadership skills, problem solving capacity, and obsession with results that distinguish entrepreneurs in the business sector. For social entrepreneurs, however, the bottom line is measured in lives. Whether it's about stopping the enslavement of children, bringing electricity to rural families, introducing affordable cataract surgery to prevent unnecessary blindness, or inventing a low-cost irrigation pump to increase the fertility of farms, each story illustrates the transforming results when an innovative idea is coupled with a strategy for action and a passion for change.
