A Few Organizations for Social Good

I try not to advocate organizations like these too much; in fact, I try to avoid advocating such organizations at all.  Nevertheless, here they are on the Web, so I figured I would make links to them.  From what I think and see and have learned, it seems to me that the issues addressed by the organizations below are more important and more urgent than other, more popular, issues such as abortion, jobs, the environment, the budget, internet "decency," and the economy.
