You, Planet: Biosphere of the Body

This is an unknown, alien world. Deep canyons and cracks scar the landscape, imposing mountain ranges tower over scorched plains, moist jungles and acidic lakes hide strange creatures unknown to most – ferocious predators, grazing vegetarians, cunning quick-change artists. But this alien planet is not from outer space. This planet is you, your skin, and the microscopic ecosystems of your body.
