I recently came across an interesting site named NothingButNets.com. This organization collects donations in order  to save lives by preventing malaria, a leading killer of children in Africa. While the UN Foundation has been working with the UN to fight malaria for years, it was a column that Rick Reilly wrote about malaria in Sports Illustrated, challenging each of his readers to donate at least $10 for the purchase of an anti-malaria bed nets — and the incredible response from thousands of Americans across the country — that led to the creation of the Nothing But Nets campaign.
