Yesterday I posted a link to the Red Cross, but there is another organization that desperately needs help in the wake of the Haitian earthquake, it's Doctors Without Borders.
Click on the link above, and please donate to this incredible organization. These are brave and wonderful people who go all over the world, into the war-torn areas where even the UN will not go, to provide medical help to those who need it.
Another good cause to donate to is Hollywood Unites for Haiti. This was founded by actor Jimmy Jean-Louis who plays "The Haitian" on Heroes. And is Haitian. So, there is yet another idea for a way to donate if you wish too.
Edit: Because Habitat for Humanity is also getting involved in Haiti. So you can always donate to them.
