Speaking of the environment, I found Health Leads to be an interesting organization. The founder, Rebecca Onie, is putting college kids to work helping hospital clinic visitors find the assistance most medical facilities are ill-equipped to provide. Things like food assistance and housing help. A number of the people Health Leads help are made sick by their environments - such as low income housing with lead paint. As our economy becomes more divided between the haves and the have-nots, these social issues are only going to grow and as a result, greatly affect the cost of healthcare in the U.S.
