Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

In Pittsburgh, the elevation varies wildly, fluctuating 660 feet from highest to lowest points throughout the area and making it one of the hilliest cities in the United States. Throughout this unruly and physically challenging landscape, the city's first mass transportation system was built—a steadily expanding network of public stairways, locally referred to as city steps, these flights of stairs are a throwback to a very different time in history and a very different Pittsburgh.

For millennia, humans have used one simple method to solve problems. Whether it's planting crops, building skyscrapers, developing photographs, or designing the first microchip, all creators follow the same steps to engineer progress. But this powerful method, the "engineering method", is an all but hidden process that few of us have heard of—let alone understand—but that influences every aspect of our lives.

On the morning of May 9, 1980, harbor pilot John Lerro was guiding a 600-foot freighter, the Summit Venture, into Tampa Bay. Directly in the ship's path was the Sunshine Skyway Bridge. Suddenly, a violent weather cell reduced visibility to zero at the precise moment when Lerro attempted to direct the 20,000-ton vessel underneath the bridge. Unable to stop or see where he was going, Lerro drove the ship into a support pier.

More than any other technology, cars have transformed our culture. Cars have created vast wealth as well as novel dreams of freedom and mobility. They have transformed our sense of distance and made the world infinitely more available to our eyes and our imaginations. They have inspired cinema, music and literature; they have, by their need for roads, bridges, filling stations, huge factories and global supply chains, re-engineered the world.

Rivers in the Desert follows the remarkable career of William Mulholland, the visionary who engineered the rise of Los Angeles as the greatest American city west of the Mississippi. He sought to transform the sparse and barren desert into an inhabitable environment by designing the longest aqueduct in the Western Hemisphere, bringing water from the mountains to support a large city. This "fascinating history" chronicles Mulholland's dramatic ascension to wealth and fame - followed by his tragic downfall after the sudden collapse of the dam he had constructed.

When it comes to climate-change-inspired threats, it is rising sea levels we hear most about. But if the oceans are, as Herman Melville put it, “the tide-beating heart of the Earth”, rivers are its circulatory system. In the United States, there is no river more storied, symbolic, and vital than the Mississippi, and none, to use Mark Twain’s word, more lawless. The struggle to control it has been going on nearly as long as there has been human civilization on its banks, and the attendant drama and dangers have been memorialized by many writers.

Beyond Control reveals the Mississippi as a waterway of change, unnaturally confined by ever-larger levees and control structures. During the great flood of 1973, the current scoured a hole beneath the main structure near Baton Rouge and enlarged a preexisting football-field-size crater. That night the Mississippi River nearly changed its course for a shorter and steeper path to the sea. Such a map-changing reconfiguration of the country's largest river would bear national significance as well as disastrous consequences.

Between 1817 and 1898, New York City evolved from a vital Atlantic port of trade to the center of American commerce and culture.

In Divided Highways, Tom Lewis offers an encompassing account of highway development in the United States. In the early twentieth century Congress created the Bureau of Public Roads to improve roads and the lives of rural Americans. The Bureau was the forerunner of the Interstate Highway System of 1956, which promoted a technocratic approach to modern road building sometimes at the expense of individual lives, regional characteristics, and the landscape.
