Beavers prevent flooding in London borough, saving millions in infrastructure costs

Ealing borough in London has successfully reintroduced beavers as a natural solution to recurring flood problems. The animals have built wetlands that absorb and retain excess rainwater during heavy storms. The area around Greenford station has remained flood-free for three consecutive years as a result. Beyond flood control, the initiative has also revived local ecosystems by attracting a variety of wildlife. The project highlights how nature-based interventions can effectively address environmental challenges at a fraction of conventional infrastructure costs.
