Have you ever driven by a highly polluted area and wondered what can be done to stop people dumping their rubbish? At the turn of the Millennium Peru city authorities tried a novel approach. Some of the streets in the capital city were scarred by terrible littering – people even stopping to urinate in the streets. The authorities responded by placing pictures of Jesus and Mary on the walls of buildings lining the most polluted streets. Why? Because the people of Peru are, on the whole, committed to Roman Catholicism. The authorities have found that people are far less likely to litter the streets under the gaze of Jesus and the Virgin Mary.
