A professor has claimed that amphibians such as frogs and toads could die when roads are gritted too much.
Dr Dan Forman, of Swansea University in Wales, says using excess gritting salt is bad for the environment as it forces amphibians living by roads to leave their habitats.
He says that the high amount of gritting salt leaves them unable to spawn in Wales where amphibians come out much earlier, the BBC reported.
