give a dog a bone (or water)
The 150,000 stray dogs in Istanbul, Turkey, pose a serious problem for the city as they wander about in search of food and water. Instead of getting rid of them or letting them starve, one Turkish company has developed an innovation that not only feeds the nomadic canines of Turkey, but helps promote recycling as well. This gigantic reverse vending machine dispenses food and water every time a bottle is recycled. Save the dogs. Save the environment. This is a win-win.
