There is no greater cause than providing humanitarian and disaster relief to those in need. Creating better schools, preserving nature, deeming significant buildings historic, saving the whales are all worthy causes, but none compare to providing safe shelter, food, water, and medicine to those desperate and without.

The Red Cross does a tremendous job in addressing these needs, and is an essential and worldwide resource. From their site:

"Thank you for considering a Red Cross donation today. Every dollar fuels our mission of doing whatever it takes to relieve and prevent people from suffering - through lifesaving programs and services in your local community, across the country, and around the world."

They respond to more than 70K disasters annually. Help fund the relief efforts of the Red Cross by making a donation today:
