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.

Plastics, Global Heating and Fish Growth?
Millions of tonnes of bisphenol a (BPA) are generated per annum in the manufacture of plastics. It is well-established that BPA is a hormone disrupter. A University of Sydney study has demonstrated that fish exposed to BPA in warmer waters, take longer to reach a given size (https://www.theguardian.com/environment/2022/jan/27/fish-growth-slowed-by-high-temperatures-and-plastic-chemical-bpa-research-shows). Climate change and pollution will make warmer waters with elevated BPA concentrations, increasingly common. The research suggests that marine productivity cycles will suffer major disruptions as a result.
