Finally, one of the most difficult (but, arguably, most rewarding) ways to help the world’s poor is through volunteering. This can encompass many different things: volunteer for a political campaign, volunteer for a nonprofit organization, volunteer for a movement to fight poverty, or grab an internship. Personally, I am an intern writing for The Borgen Project; I do not get paid, but it helps get the message out to the world. Overall, you can find volunteer opportunities online (for example, through Idealist), but there are also local opportunities that may be available if you ask around.
