I'm coming around to the idea that we should start by introducing beavers, gophers or wolves before we try solving any problem by any other approach.
The flooding at the Greenford London subway station has been reduced by around 90% thanks to... *checks notes* ...a family of beavers.
After conservationists reintroduced a group of beavers into a nearby city park, the animals began building dams, and the wetlands they created now absorb and slow floodwater naturally.
City officials had been planning major flood infrastructure works, but the beavers effectively created them on their own — while also boosting biodiversity and restoring the ecosystem around them.
I think the money the city would have spent on anti-flooding infrastructure should go to the beavers, don't you? 🦫 🦫 🦫
