And as you can see from these maps of London, in the 90 years after the trains came, it goes from being a little blob that was quite easy to feed by animals coming in on foot, and so on, to a large splurge, that would be very, very difficult to feed with anybody on foot, either animals or people.
En estos mapas pueden ver cómo Londres, en los 90 años posteriores a la llegada del tren pasa de ser un pequeño puntito, fácil de alimentar con los animales que llegaban caminando, a ser un gran derroche, difícil de alimentar con cualquiera que vaya a pie, sean animales o personas.
