The Guardian is extolling the virtues of beavers in controlling the water flow in rivers
Further down the article I found this gem, a piece of getting it arse about face worthy of a Homey:
“However, it also makes clear that those who benefit from beaver reintroduction may not always be the same people as those who bear the costs, highlighting that the reduction of flood risk in communities downstream may come at a cost of water being stored on farmland upstream.”
What he really means of course is that the people responsible for the flooding downstream, the landowners who have cleared out and straightened the rivers to stop their land flooding as it always used to, don't want all their hard work undone by a few rodents.
