There are nearly 2 million nonprofits in the United States and almost 10 million around the world.  Covering issues from human trafficking and homelesness, to literacy and domestic violence, animal rights, education, immigration, the environment, and clean water, to name a few.  And while the larger, more established entities may be more well known, there are hundreds of thousands of unique nonprofits doing interesting work of their own.  Here are a few we've found that are Just Doing Something...Anything! for issues they care deeply about.
