Question: Why are there so many mice in London?
Position‹4 of 5›: London's predator ecosystem helps mice

This position attributes London's abundance of mice to its predator ecosystem. It argues that the city strips away many of the survival threats mice face in the wild — with far fewer predators and a plentiful supply of food, urban mice thrive and multiply.

Fewer predators and more food means more mice
In their natural, rural environment, mouse populations are curtailed by an extensive array of predators and a limited food supply. In an urban setting such as London, such population restrictions are no longer a factor.
