UniversalGiving makes volunteering and donating to causes so easy. They divide up the contents on their website between volunteering and donating. Then you can choose a region (like Latin America) to look for opportunities in. I will be studying abroad in Nicaragua in the fall and UniversalGiving helped me find a bunch of opportunities that I could give my time to in order to get more involved in the community. What is great is all of the donations go to the organization that you choose-nothing goes to UniversalGiving. This is a great organization; I wish more companies today were focused on helping make the world a better place.
