The 6th great extinction event appears to be nothing like as dramatic as the asteroid collision that accounted for the dinosaurs (http://www.theguardian.com/environment/2014/dec/14/earth-faces-sixth-great-extinction-with-41-of-amphibians-set-to-go-the-way-of-the-dodo). It has been estimated that 41% of the world's amphibia plus substantial numbers of species of birds and mammals will soon be driven to extinction largely by human (anthropogenic) effects. The human desire for more and more 'agricultural land' (for biofuels as well as actual food), the 'need' for hydrochemicals and metals and our tendency to introduce (accidentally or deliberately) alien species into habitats across the world seem to be the cause of this looming mass extinction. That doesn't seem to be an especially good epitaph for our species?
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
