Dogs may be able to help humans in any number of ways, but one thing that will never change is how humans need to help dogs -- namely, by picking up their poop.
One company that specializes in picking up dog droppings, Doody Calls, recently estimated that American dogs alone let go of 10 million tons of dog poop a year. The company also found that 40 per cent of dog owners don't pick up their pets' poop at all.
In Mexico City, this issue has prompted a campaign by advertising agency DDB Mexico with a Pavlovian-style notion: Offer free Wi-Fi in public areas every time owners put dog poop into a particular bin. Though the video above looks like a satire, it's a very real initiative being rolled out in 10 parks across the city in partnership with Mexican Internet portal Terra. Owners bag the poop, put it in a bin where it gets weighed, and the park receives free Wi-Fi for the time garnered by the amount deposited (usually a few minutes).
Though meant for 'doggie bags,' the company told Creativity Online they're fine with people putting other trash into the bin -- after all, either way it keeps the area clean.
