“Imagine a city draped in a blanket of green … Is this the city you know?”

A Forest in the City looks at the urban forest, starting with a bird’s-eye view of the tree canopy, then swooping down to street level, digging deep into the ground, then moving up through a tree’s trunk, back into the leaves and branches.

Trees make our cities more beautiful and provide shade but they also fight climate change and pollution, benefit our health and connections to one another, provide food and shelter for wildlife, and much more. Yet city trees face an abundance of problems, such as the abundance of concrete, poor soil and challenging light conditions.

So how can we create a healthy environment for city trees? Urban foresters are trying to create better growing conditions, plant diverse species, and maintain trees as they age. These strategies, and more, reveal that the urban forest is a complex system—A Forest in the City shows readers we are a part of it.

Includes a list of activities to help the urban forest and a glossary.

The second book in the ThinkCities series explores water as a precious, finite resource, tracing its journey from source, through the city, and back again.
Living in cities where water flows effortlessly from our taps and fountains, it's easy to take it for granted. City of Water, the second book in the ThinkCities series, shines a light on the water system that is vital for our health and well-being. The narrative traces the journey of water from the forests, mountains, lakes, rivers and wetlands that form the watershed, through pipes and treatment facilities, into our taps, fire hydrants and toilets, then out through storm and sewer systems toward wastewater treatment plants and back into the watershed.
Along the way we discover that some of the earliest cities with water systems date back to the Indus Valley in 2500 BC; that in 1920 only 1 percent of the US population had indoor plumbing; that if groundwater is used up too quickly, the land can actually sink; and more. The text is sprinkled with fun and surprising facts -- some water fountains in Paris offer sparkling water, and scientists are working to extract microscopic particles of precious metals found in sewage.
Readers are encouraged to think about water as a finite resource, and to take action to prevent our cities and watersheds from becoming more polluted. More than 2 billion people in the world are without access to safe, fresh water at home. As the world's population grows, along with pollution and climate change, access to clean water is becoming an urgent issue.
Includes practical steps that kids can take to help conserve water.
