This morning, The Grocer newsletter included two news stories about the environment. Specifically; biodiversity. The first reported on the British Retail Consortium as it sounded the alarm over biodiversity loss threatening UK supply chains, while Science for Sustainable Agriculture told everyone to calm down. Defra’s most recent biodiversity report has it wrong, it says, claiming that the number of birds and insects on Britain’s farmland over the past 30 years has remained stable.
