"But what about the value of genuine nature – the virgin forests of Siberia, the gulls in the Wadden Sea? Don’t they still hold value, even if it is unintended? And it is precisely here that we find the invisible ecosystem services: that nature provides. Worms, along with millions of species of bacteria and single-celled organisms, keep the soil fertile so that we have maize and grain to harvest; forests filter dust from the air; insects pollinate our crops. These are invisible, valuable services provided by nature – incidental services from unintentional nature. And they are much more exciting than the value of intentional animals and plants in parks, barns and oceanariums. Those are intended, here for a reason, and so, logically they have value. But the fact that unintentional nature has value too might come as a surprise."
