Farming Versus Nature in the Norfolk Broads?

Wetlands are amongst the most endangered environments on this planet. Wetlands support a vast array of animal and plant species. A couple, at great personal expense, are (for a second time) taking England's Environment Agency to court, to stop water abstraction destroying internationally-important wetlands in the Norfolk Broads (https://www.theguardian.com/environment/2022/jun/27/environment-agency-faces-legal-battle-over-water-removal-in-norfolk-broads). The Environment Agency licences farmers on land near protected wetlands, to remove groundwater to irrigate potatoes and other crops. It's estimated that this water abstraction increases crop yields by 15-20%. A 2015 Natural England study found, however, that, over the last 50 years, water abstraction had been the major cause of extinctions in that area. The rocks of Norfolk are mainly calcareous limestones and mudstones. Water abstraction reduces the flow of calcareous groundwater. Atmospheric carbon dioxide combines with rainwater to produce carbonic acid. This makes the waters of the fens more acidic, killing rare alkaline-loving plants and their associated animals. The couple, who are themselves farmers, point out that Tourism is, by far, the biggest employer in the Norfolk Broads. They argue that, although food production is important, boosting yields should not be done, if it permanently destroys unique ecosystems.
