Our consumption is trashing a natural world infinitely more fascinating and intricate than the stuff we produce
This is a moment at which anyone with the capacity for reflection should stop and wonder what we are doing.
If the news that in the past 40 years the world has lost over 50% of its vertebrate wildlife (mammals, birds, reptiles, amphibians and fish) fails to tell us that there is something wrong with the way we live, it’s hard to imagine what could. Who believes that a social and economic system which has this effect is a healthy one? Who, contemplating this loss, could call it progress?
In fairness to the modern era, this is an extension of a trend that has lasted some 2 million years. The loss of much of the African megafauna – sabretooths and false sabretooths, giant hyaenas and amphicyonids (bear dogs), several species of elephant – coincided with the switch towards meat eating by hominims (ancestral humans). It’s hard to see what else could have been responsible for the peculiar pattern of extinction then.
As we spread into other continents, their megafauna almost immediately collapsed. Perhaps the most reliable way of dating the first arrival of people anywhere is the sudden loss of large animals. The habitats we see as pristine – the Amazon rainforest or coral reefs for example – are in fact almost empty: they have lost most of the great beasts that used to inhabit them, which drove crucial natural processes.
Since then we have worked our way down the foodchain, rubbing out smaller predators, medium-sized herbivores, and now, through both habitat destruction and hunting, wildlife across all classes and positions in the foodweb. There seems to be some kink in the human brain that prevents us from stopping, that drives us to carry on taking and competing and destroying, even when there is no need to do so.
But what we see now is something new: a speed of destruction that exceeds even that of the first settlement of the Americas, 14,000 years ago, when an entire hemisphere’s ecology was transformed through a firestorm of extinction within a few dozen generations, in which the majority of large vertebrate species disappeared.
Many people blame this process on human population growth, and there’s no doubt that it has been a factor. But two other trends have developed even faster and further. The first is the rise in consumption; the second is amplification by technology. Every year, new pesticides, fishing technologies, mining methods, techniques for processing trees are developed. We are waging an increasingly asymmetric war against the living world.
