Antarctica is a lonely continent.

But the Antarctic Peninsula, the little tail that juts out towards South America,

is a hub of human activity.

More than 50 scientific research stations are based there.

And in a recent travel season, 42,000 tourists visited, mostly from cruise ships.

Problem is, when humans go somewhere, hitchhikers come with, like a non-native flightless

midge, an insect that has already taken up residence in the peninsular region.

And its biomass is greater than the biomass of all the other invertebrates in the soil.

It's already kind of taking over
