As the world observes Day of the African Child on June 16, there's an easy step you can take to make a meaningful difference: Donate a net for just $10. It's easy to do through the United Nations Foundation's Nothing But Nets, a global, grassroots campaign inspired by sports columnist Rick Reilly. If you're looking for a last-minute Father's Day gift for a sport-obsessed husband or dad, this would be spot-on.
