it's looking bad for biodiversity and the survival of ecosystems on the planet as the 6th mass extinction is reportedly well underway (https://www.theguardian.com/environment/2017/jul/10/earths-sixth-mass-extinction-event-already-underway-scientists-warn). Scientists have recorded that billions of regional and local populations have been lost and, of the mega species studied, around half have lost 80% or more of their range. The authors suggest that human over-population and activities (the Anthropocene era?) accounts for most of this event. In spite of this, many people seem to view the losses as an unfortunate side-effect (perhaps reducing the content matter of a new series of Life on Earth) rather than a real challenge to the viability of the planet's life in its present form (i suspect the bacteria will still be around so we wouldn't be starting from scratch).
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.
