People in New Zealand have been warned not to consume 'sexy pavement lichen' in spite of its being claimed by some folk to act as a natural alternative to Viagra (https://www.theguardian.com/world/2019/aug/15/new-zealanders-warned-about-the-consumption-of-sexy-pavement-lichen). Firstly, there are doubts about its sexual benefits and, secondly, the fungus is likely to be contaminated with urine, dog faeces and pollutants from road traffic. Licking it could make consumers seriously ill rather than converting them to 'sex machines'.
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.
