Sustainability is best viewed through specific examples, or case studies. One way of conceiving sustainability is to think of it as a map that shows us connections between apparently unrelated domains or sequences of events. To cite an earlier example, what do the cornfields of Illinois have to do with the decline of fisheries in the Gulf of Mexico? To the uneducated eye, there is no relationship between two areas so remote from each other, but a sustainable systems analysis will show the ecological chain linking the use of chemical fertilizers in the Midwest, with toxic runoff into the Mississippi Basin, with changes in the chemical composition in the Gulf of Mexico (specifically oxygen depletion), to reduced fish populations, and finally to economic and social stress on Gulf fishing communities. Here, I will look at two case studies in greater detail, as a model for the systems analysis approach to sustainability studies in the humanities. The first concerns the alarming worldwide decline of bee populations since 2006, owing to a new affliction named Colony Collapse Disorder (CCD). The second case study examines the BP oil disaster in the Gulf of Mexico in 2010, considered in the larger historical context of global oil dependency.
Before the emergence of coal and later oil as highly efficient and adaptable energy sources, human beings relied on mostly renewable sources of energy, principally their own muscle power, supplemented to varying degrees by the labor of domesticated farm animals, wood and peat for fuel, and the harnessing of wind and water for milling and sailing. An extraordinary and rapid transformation occurred with the extraction of latent solar power from ancient organic deposits in the earth. On the eve of industrialization, around 1800, the raw muscle power of human beings was responsible for probably 70% of human energy expenditure, while slavery—a brutal system for the concentration of that energy—functioned as a cornerstone of global economic growth. In the 1500-1800 period, in addition to the ten million or more Africans transported to slave colonies in the Americas, several times as many Indian and Chinese laborers, under various regimes of servitude, migrated across the globe to answer labor “shortages” within the globalizing Atlantic economy.
But technical improvements in the steam engine revolutionized this longstanding energy equation. Already by 1800, a single engine could produce power the equivalent of two hundred men. Today, a single worker, embedded within a technologized, carbon-driven industry, takes a week to produce what an 18 th century laborer would take four years to do, while the average middle-class household in the industrialized world consumes goods and energy at a rate equivalent to having 100 slaves at their disposal round-the-clock.
In the famous medieval story of Faust, a scholar who dabbles in black magic sells his soul in exchange for extraordinary powers to satisfy his every desire. The Faust story provides an excellent analogy for our 200-year love affair with cheap fossil fuel energy. Our planetary carbon endowment has provided us with extraordinary powers to bend space and time to the shape of our desires and convenience, and fill it with cool stuff. But petroleum and coal are finite resources, and such is the environmental impact of our carbon-based Faustian lifestyle that scientists have now awarded our industrial period, a mere blink in geological time, its own title in the 4 billion year history of the planet: the Anthropocene . We are no longer simply biological creatures, one species among thousands, but biophysical agents, reshaping the ecology of the entire planet, and shaping the fates of all species.
