How the Brown Rat Conquered New York City (and Every Other One, Too)
A New York City rat running along a subway platform. Rattus norvegicus, otherwise known as the brown rat, remains surprisingly mysterious.
Millions of them live in New York, and billions more in cities and on farms across the globe. And wherever they scurry, they wreak havoc.
They devour food supplies and contaminate what they dont eat with feces and urine. They spread a range of harmful viruses and bacteria. In delicate ecosystems around the world, they threaten other species with extinction.
