Engineers without Borders
I went to an Engineers Without Borders conference in Montreal a while ago, and I was very impressed; these people seem to have their goals straight. And little did I know that it was founded in 2000 by University of Waterloo students who were in school at the same time I was. Considering it now has 25000+ members, that's incredibly fast growth.
Anyway, as a sample of the sort of things they do, here's a report of a field study of how a proposed drought-resistant crop worked out in a heavy rainfall season. Summary: not so well. But that's not the point; the point is that they actually went to check, and then reported the results honestly, just like you'd expect engineers to do. I really respect that.
