>"Don't go burying wild animals in my garden… or at least ask for permission first."

In the overcrowded city, nature is getting out of control.

The mice are scratching between walls, the pigeons are diseased and the foxes are beginning to rule the streets.

The problem is growing. It's contagious. It has to be stopped, before it's too late.

"People can get used to terrible things. Very quickly. If they have to. It doesn't take much for things to start to fall apart."
