NATURE'S CLEANUP CREW tells the story of the busy scavengers who live among us in our cities, recycling the mountains of waste that consumer society leaves behind. To us, it's garbage. To them, it's dinner. With the help of thoughtful and passionate scientists who have come to understand and love them, find out what makes scavengers tick and debunk myths around them and why they deserve respect. What adaptations have they evolved to do their job? What benefits do they provide humanity? How can humans work with them, so that they can do their job even better? In Manhattan, the tourist crowds are seen from the ants' point of view, as a team of young entomologists discover how important they are to keep the streets clean. In Berlin, discover how scavenging foxes have adapted to survive in an urban environment - something they've had to do because they have nowhere else to go. In Toronto, hunt for the elusive opossum to find out how they help to make our cities healthier. And in Addis Ababa, Ethiopia, track the city's growing population of vultures to find out how they protect people from deadly disease.
