The Future of Environmental Philosophy

The old guy in The Graduate had just one word for Dustin Hoffman's character, Ben: "plastics." This old guy has three words for the future pursuit of environmental philosophers, young and old: global climate change (GCC).

GCC is emerging as the central environmental concern of the 21st century. Back in the 20th century, E. O. Wilson's mantra was (I paraphrase) 'abrupt mass anthropogenic species extinction is the crime for which posterity is least likely to forgive us.' In view of the multifaceted catastrophe graphically depicted in the recent acclaimed film, An Inconvenient Truth (AIT), Wilson's dictum seems quaint. Rather, a world whose very geography will be anthropogenically altered by risen sea levels, whose weather will be increasingly violent and erratic, whose seas will be stagnant and acidified by carbonic acid, etc., etc., is the crime for which posterity is least likely to forgive us—if there is any posterity to make a judgment.

According to Al Gore in AIT anthropogenic GCC is a "moral" and "ethical" issue. But he doesn't elaborate. And at the end of the film he provides a lame list of things you and you and you and you—all of us individually AND voluntarily—can do to mitigate GCC, such as swap out halogen light bulbs for compact florescent ones and drive a hybrid car. Think "tragedy of the commons" for the efficacy of that approach to an adequate ethical response to the challenge of GCC.

Gore's naivete apart, environmental ethics (EE) as we know it is singularly ill-prepared for dealing with GCC. The problem is one of scale, temporal as well as spatial. Spatially, EE concern was focused on the scale of biotic communities, ecosystems, and landscapes. And the relevant science was ecology. Temporally, the scale was also ecological: It might take Prince William Sound half a century, perhaps even a whole century, to fully recover from the Exxon Valdez spill. In temperate climates, after a clearcut a mature forest might spring up in a century and, through ecological succession, if left alone it will return to old growth in 300 years. Back in the 20th century that seemed like a long time, and we lamented that the ecological temporal scale and the economic temporal scale of industries like the timber business and the oil business were out of phase, the former measured in decades the latter in quarters. But now, elderly environmental philosophers like me will personally witness little more than the initial environmental consequences of GCC—the occasional Katrina, the occasional hottest year on record, the disappearance of glaciers in Glacier National Park. We won't live to see (I hope) the cessation of the Gulf Stream or sea-levels rise more than a few centimeters. And the rectification of these consequences will be completed, if they ever are, only after thousands of years have elapsed.

How then do we scale EE up to meet the moral challenge of GCC? Spatially we have a huge leap to make from the landscape scale to the biospheric scale. We have to become conversant with a new set of sciences; the relevant sciences are not ecology and conservation biology, but biogeochemistry and earth-systems science.

Is a GCC EE even possible? Maybe ethics has temporal-scale limits? We used to marvel at the long view of the Iroquois who considered the consequences of present policies out seven generations. Wow! At 25 years per generation that is all of 250 years (adding on the 75-year life-span of the 7th generation). Can we have ethical concern for the 37th generation, a thousand years out? Or the 121st generation 3000 years out?
