One of the ways people become prominent in a profession is by listening to what others are saying, then saying it louder, in more auspicious settings. Leaders in that sense aren't likely to make waves, but they're very good at riding them. Reflecting the common wisdom is the source of their popularity, power and authority. Some folks toe the lines pretty carefully until they feel immune to criticism for one reason or another, then have their say. More than one of my co-authors on "Don't Judge Species on their Origins" last year in Nature fits that category. Joan Ehrenfeld knew our paper would be her final word on ecology. But you can't count on anyone being willing and able to make any particular case in their swansong. Then there are people like me who find themselves in the midst of naked emperors, but have no ambition to take their places. To take a literary/cinematic tangent, we are the ones more eager to smelt rings of power than wear them, more concerned with breaking elder wands than wielding them. So I'm not the kind of person you were hoping for in this case, but I'll say this anyway: life on earth has never been about sustainability. It's always been about individuals of the current generation--of the moment, in fact--surviving under prevailing conditions. Every generation (of every population) is born into a different world. Sometimes slightly different, sometimes profoundly different, sometimes favorably different, sometimes fatally so. Domesticating that uncertainty and aspiring to negotiate a fair deal with the ghosts of generations yet to come seems appealing at first glance. But it's naive to project our values, preferences and capabilities (maybe even our anatomies and physiologies) into an unknowable future and seek to impose them on our successors. Consider how much trouble we have wrapping the US Constitution around today's issues only nine or ten generations down the pike. Most of us are so decoupled from even the previous two or three generations to have much more than the most general idea what futures they were hoping for on our behalf. It isn't clear what ought to be sustained. It's even less clear what CAN be sustained. It's never too late to act, because it's always too early to decide.
