You can send funds.
The New York Times gives a list of aid organizations.
I was told that the
Lutheran World Federation of Churches is also a good organization to give to. They have a lot of experience in crisis management, they do not try to convert people to Lutheranism and they seem to work on issues of gender justice, too.
I cannot personally vouch for any of the above, but they are avenues to get your pennies to make a difference.
As an aside, I really want to find a way to give help to the Yazidis in Iraq. If you know of a way, leave it in the comments, with my thanks.
