"Green" accounting - adjusting the national accounts to reflect environmental data - is still in its unpromising infancy. It is complicated by the fact that ecosystems do not respect man-made borders and by the stubborn refusal of many ecological variables to succumb to numbers. To complicate things further, different nations weigh environmental problems disparately.

Despite recent attempts, such as the Environmental Sustainability Index (ESI) produced by the World Economic Forum (WEF), no one knows how to define and quantify elusive concepts such as "sustainable development". Even the costs of replacing or repairing depleted resources and natural assets are difficult to determine.

Efforts to capture "quality of life" considerations in the straitjacket of the formalism of distributive justice - known as human-welfare ecology or emancipatory environmentalism - backfired. These led to derisory attempts to reverse the inexorable processes of urbanization and industrialization by introducing localized, small-scale production.

Social ecologists proffer the same prescriptions but with an anarchistic twist. The hierarchical view of nature - with Man at the pinnacle - is a reflection of social relations, they suggest. Dismantle the latter - and you get rid of the former.

The Ethicists appear to be as confounded and ludicrous as their "feet on the ground" opponents.

Biocentrists view nature as possessed of an intrinsic value, regardless of its actual or potential utility. They fail to specify, however, how this, even if true, gives rise to rights and commensurate obligations. Nor was their case aided by their association with the apocalyptic or survivalist school of environmentalism which has developed proto-fascist tendencies and is gradually being scientifically debunked.

The proponents of deep ecology radicalize the ideas of social ecology ad absurdum and postulate a transcendentalist spiritual connection with the inanimate (whatever that may be). In consequence, they refuse to intervene to counter or contain natural processes, including diseases and famine.

The politicization of environmental concerns runs the gamut from political activism to eco-terrorism. The environmental movement - whether in academe, in the media, in non-governmental organizations, or in legislature - is now comprised of a web of bureaucratic interest groups.

Like all bureaucracies, environmental organizations are out to perpetuate themselves, fight heresy and accumulate political clout and the money and perks that come with it. They are no longer a disinterested and objective party. They have a stake in apocalypse. That makes them automatically suspect.

Bjorn Lomborg, author of "The Skeptical Environmentalist", was at the receiving end of such self-serving sanctimony. A statistician, he demonstrated that the doom and gloom tendered by environmental campaigners, scholars and militants are, at best, dubious and, at worst, the outcomes of deliberate manipulation.
