People spend countless hours searching for entertainment in the natural world; they travel to rainforests, beaches, mountains, and other breathtaking places, just to catch a glimpse of this remarkable planet. We could all save a lot of time and money, and see something just as amazing, by taking a closer look at ourselves. Our skin is a vast land of complex ecosystems; from the extensive desert plains of our chest and stomach, to the great fertile masses of the underarms and genitalia, the epidermis is teeming with over a thousand species of bacteria. Although they occupy all parts of the body, like humans, the trillion or so inhabitants generally congregate in the more fruitful areas. A large city like New York would probably develop in a moist location like the fold between your toes; the cheeks of your arse are less desirable to the bacteria and sparsely populated like the deserts of Australia. We are providing the environment and are therefore comparable to the planet we call home. We subject our occupants to harsh conditions similar to those we endure ourselves. Bathing in the sun might cause serious drought, a brisk stroll may generate strong winds, and showering will probably lead to harsh storms. A quick dip in the ocean could cause a flood that wipes out an entire species.
