Nancy and Jake are farmers. They raise their cows and pigs, and grow their crops. They use a lot of big machines to help them, and spray a lot of chemicals to get rid of the weeds and the pests. That's what all good farmers do, isn't it? And yet, there is no wildlife living on their farm. The animals look sad. Even the trees look sad! One day, Nancy has an idea... what if they stopped using all the machines, and all the chemicals, and instead they went wild?

The author's own experience of rewilding her estate at Knepp has influenced conservation techniques around the world that are bringing nature back to the countryside and bringing threatened species back from the brink.
