My chief reservation about sustainability is that it can mean so many things to different interest groups. For one protagonist, sustainability may demand a massive redistribution of resources and wealth, coupled with radical reassessments of consumer values and economic practice; for another, it involves no more than modest adjustments to what we already do in order to accommodate a few of the most urgent ecological imperatives.
As with Climate Change, then, thereâ€™s no overall consensus concerning the precise shape sustainability will take. â€˜Sustainable forestâ€™ can mean a rich and ancient woodland drawn upon occasionally but left mostly to its own devices, or it can be a perpetual pine plantation supplying wood pulp and with practically zero biodiversity in it.
Thatâ€™s why Iâ€™ve chosen mercury as a metaphor for sustainability. It challenges any assumption we might have that sustainability takes a uniform or consistent form among those considering it.
The image of mercury scurrying across a surface is familiar to most people, and is apt here because it allows us to better grasp the current ungraspability of sustainability. Sustainability is a fraught and fugitive issue, beset by political and personal evasions and manoeuvrings.
Whatâ€™s more, the way in which sustainability can be made to adapt shape is both weakness and strength. On the negative side, if mercury is mishandled it becomes a toxic nuisance; likewise, sustainability can be distorted, misrepresented or misapplied, either through ignorance or cynically, to allow damaging practices to continue beneath a veneer of acceptability.
On the positive side, if put to proper use in a careful and structured way, and if its complex nature is understood and worked with, sustainability also provides an extremely valuable, if not life-saving, tool.
Mercury can communicate what the weatherâ€™s doing outside, or signal the degree of fever in the human body; sustainability, too, could be harnessed to monitor and sustain the wellness of our species in relation to its environment. Either that, or we can let the concept mess with our brains and slip through our fingers.
