Admittedly, this presenter ( presumably chosen to appeal to the lucrative 18-35 advertising market) emitted a nervous laugh as he said it, like a castrated hyena coughing up furballs, because there clearly wasn't enough space between the narrow walls to swing a kitten, let alone plant every tree that is pleasant-to the sight and good for food, support every beast of the field and bird of the air, and locate the source of a river that feeds the Pishon, Gihon, Tigris, and Euphrates (sorry. I've never quite got over Sunday School).
