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.

Lemming Tracks
The lemming is a Scandinavian rodent. It was suspected of becoming suicidal, as it migrated from areas of overpopulation. The animal carried on its movement, even when that mean't the beast going over a cliff into a fjord. The interpretation turned out to be an anthropomorphism (ascribing a human characteristic to an animal). When the lemming starts its migration, it becomes negatively geotaxic (it heads downhill). The geography of Scandinavia is such that most routes end in fjords. There is now a concern, by Scottish mountaineering charities, that Google maps is inducing 'suicidal' behaviour in humans (https://www.theguardian.com/technology/2021/jul/16/google-maps-suggests-potentially-fatal-routes-up-ben-nevis-say-mountain-charities). Google maps directs people, from car parks, along 'potentially fatal' routes to the summit of Ben Nevis (the UK's highest mountain). These routes, would be difficult even for experienced climbers. Day trippers, no chance! The charities also point out that Google maps specifies other dodgy routes for other Munros (mountains over 914m). At least one, takes walkers over a cliff. I guess people need reminding that routes are for guidance only. There were lots of early claims of people resolutely following their car's satnav into the sea!
