Using a method called hydroponics, farmers can circulate water infused with mineral nutrients through the network of life-sustaining shelves. Humans also need vitamin D to maintain bone health. The best-known source of vitamin D may be sunlight exposure which encourages our bodies to produce vitamin D on its own , there are plenty of other ways to get your hands on the good stuff.
In , Slate reported on how a Russian cult survived underground , thanks in part to vitamin D-rich foods. So long as we can continue to farm animals in our earthen abodes, egg yolks, fish, milk, and cheese will keep us in the clear. Sunny dispositions might also be at risk. Though some SADs sufferers may need antidepressants, therapy, or other forms of support, carefully-planned light therapy can reduce many of the most severe symptoms.
But things are liable to get a lot worse sub-surface. When isolated in caves without light, humans have been documented to sleep for as much as 48 hours at a stretch. Using artificial lights to regulate Circadian rhythms will be another essential component of any subsurface world. Lawrence Palinkas is a professor at the University of Southern California and an expert in extreme environments. Typically, he says, people are screened for traits that would allow them to thrive in a stint aboard the International Space Station, or a sabbatical at a remote research outpost in the Antarctic.
Characteristics like openness to new experiences, for example, are often deemed essential. But a motley crew could do alright, too, if they work together. Educators could disseminate the information and tools people need to thrive underground.
Many of the subterranean spaces take advantage of existing mines, while others are made fresh with local mining equipment. The "dugout" homes are cheaper to build than conventional units and require little air conditioning, a boon in an area where average daily temperatures approach degrees in the summer.
Want your own luxury cave? The Cave House has no water bills, thanks to a natural spring, or heating or cooling bills. It does have an efficient pellet fireplace, as well as a guesthouse, workshop, shed, carport, hot tub, barbeque area and separate office and library.
The truly unique Cave House sits on a spectacular 37 acres, at 5, feet above sea level and with a rise of 2, feet. There are sweeping views of the Mule Mountains and canyon, as well as a refreshing natural creek, with natural swimming pools and gorgeous rock patios. The area surrounding The Cave House is popular with birders and wildlife viewers, supporting 79 species of birds, species of butterflies, ringtail cats, foxes, skunks, deer, squirrels, lizards, frogs, snakes, and coatimundi.
The Cave House boasts a sunroom, two bathrooms, and attractive tile flooring. It was built in and is 2, square feet. For centuries people lived in homes carved into the soft sandstone of the Kinver Edge escarpment, on the border of Staffordshire and Worcestershire in England.
The most famous cluster was under Holy Austin Rock , which at one time served as a hermitage. The last cave dwellers moved out in the s, but the site is preserved by the National Trust , which has restored some of the cave houses to the Victorian period. Some observers have wondered if the cave homes and their small cottage gardens had inspired J. Tolkien in his imaginings of Hobbits, since he grew up nearby. Cave homes have long been popular in parts of the Mediterranean region, from Turkey to Spain, Greece and Morocco.
In Spain's Andalucia, one can find numerous listings for comfortable cave houses for sale and rent , typically at prices that beat above-ground offerings. Successful cave dwellers work with what they have. Eighteen years ago in Dawson, you could watch the fishing boats docking, and even trade few beers for a freshly caught King salmon.
No one can do that anymore. Over the years, plundering has taken its toll. The First Nations — the various indigenous communities in Canada — have called for a complete ban on Yukon River Chinook salmon fishing. For years, Alaska has refused, but faced with the dwindling numbers, this is the first year that the closure has hit both sides of the border.
Life is ruled by the river, like a moody spouse. It dictates your mode of transportation: boats and canoes in the summer; skis, snowshoes, and Ski-Do in the winter.
Some years, high waters flood the cave. The water rises a foot or two a day, transforming your home into an indoor swimming pool.
Cave ceilings are much lower and harder. One morning, shouting from across the river stirred Bill from slumber. Clutching his noggin, he blacked out and fell into a shelving unit. He slowly regained consciousness under the rubble of wooden planks, paperbacks, batteries, knickknacks—still late for work. Ignoring his throbbing head, Bill sprinted down to the river and got his ass into gear. Fastening his life jacket, he noticed a pen sticking out from the back of his hip.
Dawson is a dynamic little town that belongs to the world as much as the residents. The gold rush put Dawson on the map, and because of that, people from all over the world flock to this mythic place. But it does. This pint-sized town is hopping with artists, environmentalists, teachers, dancers, trappers, art galleries, and bars.
Respect nature. Enjoy its offerings in moderation, and humbly marvel at wildlife from afar. That animal may look cute and cuddly, but keep your distance. One year, a moose and two calves were seen swimming across the river into town. It will just be a clusterfuck: one calf ends up ashore on your front lawn, while the other drifts down river.
Leave those moose alone; let them figure out where they want to go. Keep a can of bear spray in the shed flammable! The Yukon has half as many grizzlies and black bears as there are people. Word travels far about the caveman in Dawson City. Some days, it feels like the TMZ Hollywood Tour: visitors offload on the shore from boats or floatplanes; tourists cruise past in the steamer, snapping photos of your hole in the wall.
Reporters show up, taking notes and photographs, but rarely send copies of the articles. You may need to get an agent. Sometimes, you dream about building a schooner and perhaps sailing to Iceland.

In western Canada, a controversy brews once again over the capture and cull of herds of wild horses. In remote villages across Alaska, residents are fighting a desperate battle against global warming.
