This massive and continuous exposure enabled the cholera bacteria to adapt to human bodies and make us their new host. By the end of the nineteenth century, humans occupied 90 percent of the Sundarbans and were unwittingly working and bathing in water full of cholera-bearing copepods. In a way, this turned out to be true, since at the time the area was swarming with cholera germs carried by tiny flea-like creatures called copepods.īut around 1760, the East India Company took over the area, cutting down the forest to cultivate rice. Take, for example, the Sundarbans, a large mangrove forest in Bangladesh and India that was left uninhabited by Mughal emperors who saw it as a dangerous and evil land.
Well, sometimes this grand expansion comes with serious consequences. You can even find us in inhospitable places like the wetlands and Antarctica. Have you ever stopped to wonder, is there a place on Earth humans haven’t inhabited? Over the past few centuries we’ve expanded to almost every region on this planet. As humans spread across the globe, previously harmless animal pathogens adapted to our bodies and made us sick.
