Digging up trees and digging more drains isn't preventing floods.
In his latest Guardian article, George Monbiot investigates a 'major research programme, which produced the following astonishing results: water sinks into the soil under trees at 67 times the rate at which it sinks into the soil under grass. The roots of the trees provide channels down which the water flows, deep into the ground. The soil there becomes a sponge, a reservoir which sucks up water and then releases it slowly.'
