Atheist Volunteers lists many opportunities for atheists to help make this world a better place without condoning religion by association. If you want to sponsor a child, a refugee family, support an atheist in a foxhole, contribute to research for autism or MS, or donate blood on national prayer day, this site might provide the connection you need to do your good deed without religious connotations. I should mention, those are just a few of the items listed on how you can help make this world a better place by volunteering or donating time, money, or other resources.

FTC Canada (Feed the Children Canada) and Feed the Children U.S. are two other secular venues through which one can contribute charitable works without supporting religion.
