Before 2020, the daily rhythm of large cities was organized around the office. Each weekday morning, millions of workers traveled into central business districts, and their spending on trains, coffee, and lunch supported a dense network of urban services. When the pandemic forced employers to send staff home, most observers predicted a quick return to former patterns once offices reopened. Instead, remote and hybrid work proved remarkably durable. Years later, many professionals still worked from home part of the week, and the city was reorganizing itself around this new reality.

The most visible consequence was a fall in demand for office space. With fewer employees present, companies took smaller floors or left entirely, and vacancy rates in some downtown towers climbed to record levels. Owners of older buildings faced an uncomfortable choice: renovate, find a new use, or accept falling rents. Converting towers into apartments attracted attention because it promised to solve two problems at once: removing surplus offices and adding homes to districts that emptied at night. In practice, however, conversion is neither simple nor cheap. Many towers have deep floor plans, plumbing concentrated in a central core, and windows that cannot open — features that resist residential use — so only a minority of empty buildings are realistic candidates for conversion.

A second set of effects involved the businesses built to serve commuters. Lunch restaurants, dry cleaners, and shoe-repair shops lost their most predictable customers, while public transit systems lost the fares that had long subsidized service for all riders. Some businesses followed their customers into residential neighborhoods, where remote workers now bought coffee and meals closer to home. Sociologists describe this redistribution of economic activity — thinning at the center, thickening in a surrounding ring — as the doughnut effect. Transit agencies, however, had little room to adapt. Reduced ridership forced service cuts that made trains and buses less convenient, discouraging still more riders and threatening a self-reinforcing cycle of decline.

Whether these changes will prove permanent remains a matter of debate. Some executives insist that offices are essential for training, collaboration, and corporate culture, and several large firms have ordered their staff back full-time. Yet surveys show that workers rank flexibility among the benefits they value most, and employers who offer it recruit from a far wider talent pool. What appears certain is that the downtown of the past, wholly dependent on a captive weekday population, is unlikely to return in its old form. Urban researchers argue that the cities most likely to thrive will be those that give people reasons other than obligation to be present: housing, culture, green space, and streets designed for residents, not just rush-hour commuters.

— PASSAGE 2 —

Rewilding is an approach to conservation that seeks to restore ecosystems by allowing natural processes to resume with as little human management as possible. In many cases this involves reintroducing species that people previously eliminated from a region, particularly keystone species — organisms whose influence on their environment is far greater than their numbers would suggest. The approach differs sharply from traditional conservation, which often manages habitats intensively in order to preserve a landscape in a particular, chosen state. Rewilding, by contrast, accepts that ecosystems are dynamic, and its goal is not a fixed historical scene but a self-sustaining system that can evolve on its own.

The most famous demonstration of the idea followed the reintroduction of wolves to Yellowstone National Park in 1995, after an absence of roughly seventy years. With a major predator restored, elk, which had grazed heavily along riverbanks, began avoiding open valleys where they were vulnerable. Released from constant browsing, willows and aspens along the streams recovered, and their roots stabilized eroding banks. Beavers returned to build dams in the renewed thickets, creating ponds that sheltered fish, amphibians, and waterbirds. Ecologists describe such a chain of effects, flowing from a top predator down through an entire food web, as a trophic cascade. Researchers caution, however, that climate, hunting, and other predators also changed during the same period, so the wolves alone probably cannot explain every recovery that was observed.

In Europe, rewilding has found an unexpected ally in rural abandonment. As younger people have moved to cities, farmland across the continent has fallen out of use, and conservation organizations have purchased or leased large areas where European bison, wild horses, and beavers have been reintroduced. Freed rivers, with old dams removed, allow fish to reach former spawning grounds, and beaver wetlands slow floodwater while storing carbon in wet soils. Supporters also point to economic benefits for struggling rural communities, since visitors drawn by wildlife tourism spend money on local guides, food, and lodging.

Rewilding nevertheless attracts serious criticism. Farmers near rewilding areas fear — sometimes with reason — that returning predators will attack their livestock, and compensation schemes do not always remove the conflict. The approach also requires very large, connected areas to work, and it raises a difficult question: because ecosystems have changed for centuries under human influence, there is no single obvious historical state to aim for. Finally, rewilding demands patience, since the processes it sets in motion may take decades to mature. Its advocates reply that these are arguments for careful planning and local support, not for abandoning the idea.
