Left orthodoxy maintains that the story of man's interaction with the ecosphere is a story of habitat degradation leading to species extinction. That's the headline. But by overstating the risks of climate change, and underestimating the capacity of humans and other species to adapt, we risk missing the chance to address real, pressing, soluble environmental problems.Scientists at James Cook University last week announced they have discovered an exquisite new species of pygmy seahorse, 200 kilometres off the coast of Cairns. At less than half a centimetre long, the tiny creature may be the smallest vertebrate.The discovery adds to the work of 2700 scientists from 80 countries who just completed the first Census of Marine Life. The census increased the estimate of known species from 230,000 to 250,000, finding "an unanticipated riot of species, which are the currency of diversity".A startling find is the "rare biosphere" of microbes - species surviving in numbers of less than one in 10,000. These tiny cohorts subsist among masses of a dominant competitor, apparently waiting and hoping that conditions will change to allow their moment on the evolutionary stage. They seem to be a planetary insurance policy so that even if nutrient or temperature conditions change over time, there will still be an abundance of microscopic sea life in the food chain.Outbreaks of the crown of thorns starfish on the Great Barrier Reef have reduced by half over the past decade. Scientists have no way of explaining their pattern of aggression and regression but it is clear that runoff from the farmers of north Queensland is not the main culprit.Our lack of perspective derives in part from shortness of memory.
The rest here.
