Yumm Search 作成者: Yumm.com

This extension changes your default search engine to Yumm.com, where every search makes a donation to end world hunger. It also sets your new tab page to Yumm.com so you can see the impact you're making.

More precisely, all net revenue generated from the ads you normally see when you search is donated to the World Food Program and directly feeds hungry people around the world.
