Today is the 4th anniversary of the martyrdom Sr. Dorothy Stang. Basically she was a great SND to despite threats stayed in Brazil to fight against people cutting down the Amazon. Sadly, she brutally murdered by three men as she was walking to a community meeting. I encourage everyone who does not know about her to read more about what she did.

I want to note that while a great woman, she is not unique. I consider her to be a typical SND put into a terrible situation. In my second year working with SND's I continue to be dumbstruck with their commitment to service.
