We have previously written about the very real potential entrepreneurs have for solving some of the most difficult problems in the world. For the first time, Forbes has created a list of the top 30 impactful social entrepreneurs. They define social entrepreneur as an individual “who uses business to solve social issues.” The list includes entrepreneurs like Jordan Kassalow who sells ready-made reading glasses to communities in the developing world. An article from Forbes introducing the list offers some highlights:

Sam Goldman and Ned Tozun, of D.Light Design, manufacture inexpensive lamps and sell them in communities that don’t have reliable electricity.

Tom Skazy dropped out of Princeton to create Terracycle, which sells fertilizer and over 250 products made from 60 waste streams. Jane Chen’s company manufactures a sleeping bag-like device called the “Thermpod,” which warms low-birth weight babies in hospitals and clinics that have unreliable electricity and heat lamps that don’t always work.
