There’s much that needs to be done to assist the recovery in Haiti, but the consensus of those on the ground is that what’s needed now is money. Don’t mail blankets or whatever, just let the aid agencies buy what they need and ship it in. The airports and seaports are clogged and there’s minimal capacity to offload supplies, so let the aid groups make decisions about what’s needed and when.
The Intersection has a good roundup of the top aid groups. Personally, I’ve always been happy with Oxfam. They have a longstanding presence in Haiti, and I know that they’ll be working not just on the immediate relief effort, but ensuring that the long-term recovery is sustainable and more resilient and people-friendly than what came before. Oxfam really does apply the “teach a man to fish” model of aid, which is what Haiti needs.
You can also give via the Richard Dawkins website, where a bunch of nonbeliever/freethought groups are funneling donations to the Red Cross and Doctors Without Borders. I’d suggest just giving directly to those groups, but the site is set up to pass all the donations directly to the aid groups, without taking any processing fees along the way. The idea is to show how much nonbelievers give and to fight the perception that nontheists are less generous than theists.
I find the pissing match a bit unseemly, but the project seems fiscally sound and genuinely helps people in need. As always, your motives matter less than your actions.
