I drove up and down the A1 yesterday and other than the amount of blown tyres remnants, I was utterly saddened to see so many dead animals on the side of the road. There were deers, foxes, bunnies, birds of prey, magpies and unidentified remains.
I don't even want to imagine the amount of little ones I could not see, absolutely heartbreaking.
A few bridges here and there might be useful but where the road is level with the ground, will the animals understand they have to get to the bridge to cross? It seems quite a hassle, why don't we instead build all the motorways underground, the wildlife would not have to suffer anymore. (Yes I know it's a terrible idea but one can dream right?)
