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.

Sea Salad?
The Algae, Sea lettuce can be grown on ropes, suspended in shallow water on 'sea farms' (https://www.theguardian.com/environment/2022/apr/19/sea-farmed-supercrop-how-seaweed-could-transform-the-way-we-live). Sea farms for Sea lettuce are being developed in many locations, like Sweden's Koster Archipelago. Growing this algae requires no land or freshwater. Both of these are often in short supply for traditional agriculture. In Spring, Sea lettuce contains 30% protein, making it competitive against meat and soya. It also fits well with diets becoming less dominated by animal proteins. This algae can also be sourced for materials, used to make plastics. These are plastics without petroleum. It seem likely that 'lavabread', as it is called in Wales, is on its way to become a 'super-crop'. Farming the sea might have real future relevance. The farms would be less prone to substantial temperature rises, than land-based operations. There would also be fewer ethical problems than with salmon farming?
