What could be more summery than a quick dip in the pool and a giant glass of iced tea? A brisk scrub-a-dub-tub to get the popsicle goo off your legs?

We’re lucky in the US; more than a billion people worldwide don’t have access to fresh, clean drinking water. (To help out people worldwide, check out Lifestraw and donate to provide a family with an incredibly simple device that can help them filter their children’s water). How can we ensure that our kids remain so fortunate?
