I hold these truths to be self-evident:
We live on a small not very distinguished planet, circling a small not very distinguished star on the edge of nowhere in particular.
The surface of the planet has developed over billions of years.
The present day plant and animal species have evolved over tens of millions of years.
The present day ecosystems have developed over tens of thousands of years.
The life support systems – air, water, soil – for these ecosystems have been modified by the organisms themselves to create and maintain their own favourable environments.
One animal species, one of the thousands of mammal species, Homo sapiens, evolved in the last million years or so, and like all other species, relied for survival on the life support systems of the planet.
Homo sapiens, like a few other species (rabbits, beavers, termites, army ants, swallows, galahs, corals, tapeworms, pine trees, gum trees, blow flies), extensively modifies its own habitat in ways that are detrimental to other species (and itself).
Seven billion members of the species Homo sapiens have found ways to modify the environment so extensively that they are not only damaging the habitats of all species, including their own, but are degrading the fundamental life support systems of all species.
As a result many species have already gone extinct in the last few hundred years, each loss with a feedback effect causing more damage to the ecosystems they came from.
A continuation of this trend will result in a massive loss of species, and, at the very least, a massive reduction in numbers of the Homo sapiens population.
Ultimately this trend will result in the loss of all life on this small planet on the edge of nowhere.

Now all of that chain of logic seems to be rejected by conservative politicians, big business, and the shock jocks of print and radio. As best I can tell (because they never pause to examine their own assumptions) the truths they hold to be self-evident are as follows:
We live on an infinitely big planet in the centre of the universe.
The planet is a kind of terraformed billiard ball, a round and if need be empty stage on which humans strut their stuff.
Humans are not an animal species.
The planet is infested with plant and animal species, which are either domesticated for human use or are weeds and ferals.
Humans were put on the planet by an invisible supernatural being who told us to do with the plants and animals what we will.
Any plants and animals not domesticated are best got rid of because they are a waste of space (except for any which can be used for entertainment in zoos and circuses).
Humans have no need to rely on any so-called environmental life support systems, we make our own.
We can make any modifications to the soil that suit us, and add any chemicals in any amounts that suit economic objectives, to the air and water, with no negative effects of any kind.
If we clear all those unwanted life forms from the planet there will be much more room for people, whose population potential is then absolutely unlimited. Ten billion, twenty billion, you name it.
Never ending exponential growth in human numbers is good, indeed essential, because it allows exponential growth in corporate profits, and therefore the fortunes of rich people.
Those who turn the environment into profit by destroying it are heroes. Those who try to slow down the destruction should be strung up from lamp posts because they hate humans.
So where does this irrational train of thought come from? Well, some is from the old “you can’t teach a man something if his livelihood depends on his not knowing it” observation, and this, in large part, explains the anti-conservation ethos of the union movement. An ethos, incidentally, in which the workers once again, unknowingly, act for the benefit of the bosses and against their own interests. And some is from the new “you can’t teach a man something if his massive profit levels depend on his not knowing it” observation which I just made. Some of course comes from the religious self-serving proposition that man was given “dominion” over the animals. And I think religion plays a role even beyond that. Most obviously in the case of American fundamentalists who believe that any moment now they will be whisked away to heaven so who cares what, if anything is left behind, and indeed, destroying the Earth will hasten the day when “The Lord” takes us away from all this. While the rational among us can laugh, through the tears, at this kind of nonsense, I suspect that among many ordinary religious people there are variations on this belief, hidden away, perhaps unknowingly.

A new technique has recently been developed by conservatives as part of the camouflage net under which all kinds of antisocial activities can occur. Anyone who points out the growing and deliberately nurtured gap in economic status between rich and poor, or who points out, say, the disparity of government funding to public and private schools, or the different access to good health care enjoyed by different socio-economic groups, is accused of “class envy” and engaging in “class warfare”. The rich, you understand, are not engaging in class warfare as they set about massively increasing their share of the economic pie, it is the poor, those ungrateful wretches, unwilling to tug the forelock, properly, as the lord rides by on his white charger, in his red porsche. Giving words totally opposite meanings to those they once enjoyed, has the desired effect of so debasing language that we no longer have words for real concepts like “class warfare” and therefore can no longer discuss them or be aware of the process in action, as Orwell knew (“In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it”).
The aim of those who accuse people trying to conserve the world environment which six billion human beings absolutely require for survival of being “misanthropic” is similarly to remove our ability to discuss and recognise what is really going on. No coincidence in the identical semantic tricks being employed. For the richness of the rich to keep exponentially expanding at the expense of the poor three things need to happen. The pay and conditions of the working class need to be reduced by removing their protections; the share of the economy devoted to the public good (schools, hospitals, infrastructure, communications) needs to be reduced, preferably to zero; and both the parts of the environment being protected (national parks, wilderness), and the real environmental costs of development (greenhouse gases, oil spills), need to be reduced, again, preferably to zero.
By calling those who both recognise and object to these things class warriors and misanthropes, when the opposite is true, is an attempt to silence us by a perversion of the English language. Call them on it every time it happens, reclaim the language for the real world on the small planet.
