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.

A New Broom or Gorse of Course
Broom and Gorse are both members of the Pea family. Gorse is the yellow-flowered plant with protective spines. Both plants grow very well on marginal agricultural land in large areas of Scotland and Wales. Gorse (especially) is frequently periodically cleared by processes, such as controlled burning. Wendy Russell (University of Abedeen) has pointed out, that the Gorse and Broom plants respectively contain 17 and 21% protein. Burning generates 'greenhouse gases' whilst the plant's protein content is destroyed (https://www.theguardian.com/environment/2022/jan/10/protein-from-gorse-bushes-could-feed-millions-of-people-says-expert). Livestock and fodder production are relatively inefficient. They occupy 83% of UK farmland but only generate 18% of the protein consumed by humans. Russell suggests, that the protein in 'cleared' gorse, can be used to manufacture animal feed. That would reduce the land required for fodder production. If (when?) that product's safety is established, Russell sees no reason why humans couldn't directly eat it. Sixty percent of UK people are reportedly willing to try plant-based alternatives to meat and dairy products. Broom and gorse could, consequently, be efficiently 'farmed', producing enough protein to feed millions of people. Broom and gorse would also be more useful in rewilding processes, as well as reducing UK farming's carbon 'footprint'..
