Sandra Steingraber is an ecologist, an author and, now, an activist. She writes a regular column for Orion magazine and has written several books, including her latest Raising Elijah which is about how to make sure one’s children navigate a world that is fraught with environmental dangers. She knows about this firsthand from another book she wrote, Living Downstream, which is about her own battle with cancer that was caused by toxins. (The book is also a documentary by the same name). Steingraber has also become a leading voice in the nation-wide battle about natural gas and fracking.
