During his three terms as mayor of Curitiba, Brazil in the 1970s and ‘80s, architect and urbanist Jaime Lerner transformed his city into a global model of the sustainable and livable community. Through his pioneering work, Lerner has learned that changes to a community don’t need to be large-scale and expensive to have a transformative impact—in fact, one block, park, or a single person can have an outsized effect on life in the surrounding city. In Urban Acupuncture, his first work published in English, Lerner celebrates these “pinpricks” of urbanism—projects, people, and initiatives from around the world that ripple through their communities to uplift city life. With meditative and descriptive prose, Lerner brings readers around the world to streets and neighborhoods where urban acupuncture has been practiced best, from the bustling La Boqueria market in Barcelona to the revitalization of the Cheonggyecheon River in Seoul, South Korea. Through this journey, Lerner invites us to re-examine the true building blocks of vibrant communities—the tree-lined avenues, night vendors, and songs and traditions that connect us to our cities and to one another.

Gonorrhea. Bed bugs. Weeds. Salamanders. People. All are evolving, some surprisingly rapidly, in response to our chemical age. In Unnatural Selection, Emily Monosson shows how our drugs, pesticides, and pollution are exerting intense selection pressure on all manner of species. And we humans might not like the result.

Monosson reveals that the very code of life is more fluid than once imagined. When our powerful chemicals put the pressure on to evolve or die, beneficial traits can sweep rapidly through a population. Species with explosive population growth—the bugs, bacteria, and weeds—tend to thrive, while bigger, slower-to-reproduce creatures, like ourselves, are more likely to succumb.

Unnatural Selection is eye-opening and more than a little disquieting. But it also suggests how we might lessen our impact: manage pests without creating super bugs; protect individuals from disease without inviting epidemics; and benefit from technology without threatening the health of our children.

In one hundred years, or even fifty, the Arctic will look dramatically different than it does today. As polar ice retreats and animals and plants migrate northward, the Arctic landscape is morphing into something new and very different from what it once was. While these changes may seem remote, they will have a profound impact on a host of global issues, from international politics to animal migrations. In Future Arctic, journalist and explorer Edward Struzik offers a clear-eyed look at the rapidly shifting dynamics in the Arctic region, a harbinger of changes that will reverberate throughout our entire world. A unique combination of extensive on-the-ground research, compelling storytelling, and policy analysis, Future Arctic offers a new look at the changes occurring in this remote, mysterious region and their far-reaching effects.

In Roads Were Not Built for Cars, Carlton Reid reveals the pivotal—and largely unrecognized—role that bicyclists played in the development of modern roadways. Reid introduces readers to cycling personalities, such as Henry Ford, and the cycling advocacy groups that influenced early road improvements, literally paving the way for the motor car. When the bicycle morphed from the vehicle of rich transport progressives in the 1890s to the “poor man’s transport” in the 1920s, some cyclists became ardent motorists and were all too happy to forget their cycling roots. But, Reid explains, many motor pioneers continued cycling, celebrating the shared links between transport modes that are now seen as worlds apart. In this engaging and meticulously researched book, Carlton Reid encourages us all to celebrate those links once again.
