还记得《流浪地球》中的情节吗?地球表面温度下降到零下80多度,人类被迫离开了熟悉的地面,来到了地下。 特殊年代里“地下城”成为了地球居民的栖身之所。你是否想象过,如果地球真有一天面临灾难,人类是否可以永久居住于地下呢?

Can Our Civilization Live Underground?

Today, many overpopulated cities face serious expansion issues. They can no longer build up or out, so they build down. Some countries are investing in underground living, but only for short periods, where people would go, for example, to sleep after an entire day’s work.


But what if civilization completely collapsed on the surface due to global warming or a terrible catastrophe? Could humanity live permanently underground?


We need to understand much to answer this question, so let’s dig deep and see if our civilization could go full subterranean.


Indispensable resources


The first thing that comes to mind when thinking about the possibility of retreating underground is where we’re going to get water, power, and food. And while these things are necessary for us to survive, they won’t be enough if we actually what to live “down under”.


A lot of planning and supplies, a capable maintenance team, and seamless mechanisms to handle all the psychological issues involved would be good… for starters.


Power sources


Suppose a disastrous event sent us packing underground. In that case, it’s safe to admit that any power sources we relied on while living on the surface are gone.


Plopping down solar panels might not be possible. Depending on surface conditions after a disaster, we probably wouldn’t be able to venture out to maintain them, and there’s always the chance that they wouldn’t get any sun, anyways.


At this point, our better shot would be digging down instead of up and trying to take energy from the Earth itself. We could take advantage of geothermal energy, provided by the heat of our planet’s core, extracted from hot water and rocks.



Speaking of water, there’s no way we would be able to leave our bunkers to go fetch some after a cataclysmic event hit us. If the surface was hospitable enough, we could set up a rainwater collector, but that wouldn’t provide enough water for everyone (and who knows what’s in the water?)


Luckily, underground we can find naturally occurring aquifers containing groundwater. This would work as a great source of water, provided we could purify it before consuming it and contain the source before it flooded us.




Stocking up on canned food and other non-perishable meals would be a great idea, but it would only last for a short while. If we could bring farm animals with us underground, that could work, but we would need a way to sustain them if they were to sustain us. But we can’t forsake the vegetarians!


Hydroponic gardens are commonly used nowadays and could be a valuable source of leafy greens, vegetables, herbs, and fruit underground. This agricultural concept would allow us to save space and water while still providing food with a high nutrient content that could potentially sustain us all.




No one ever wants to address this stinky bit, but we would have to find a way to manage sewage and wastewater successfully. Simply letting it pile up somewhere around us wouldn’t end up well, as we’d get sick pretty quickly.


Depending on the crops we plant, we might consider using the waste as fertilizer, but we would need some proper ventilation. If we managed to build into a mountain or somewhere that’s still above sea level; we might try to find a water source that could drain the waste away to the ocean (it’s not like we’d be worried about the environment after a total catastrophe).


Overcoming fears


For many people, the idea of being confined underground can be terrifying. Not seeing the sun, not being able to breathe fresh air, not being able to get away in the case of a fire or flood, and even the idea that everything will collapse are some of the anxiety-inducing thoughts that cross people’s minds.


Gunnar D. Jenssen, a researcher at SINTEF, in Norway, who studies underground psychology and space design, found that about 3% of people are severely claustrophobic. Still, there are some ways to counter their fears.


“If you give these people something that gives them perceived control over the situation, they accept being in it. That is the key,” Jenssen said. He added that clean air and space are essential in these situations. Or at least a perception of space created by an illusion.


Jenssen worked on 4 of the longest tunnels in the world, creating illusions of space by adding well-lit oases with palm trees and sky illusions along the route. “You have a feeling of breathing space, a feeling of being outside, even though you’re 1,000 meters underground going through a mountain,” he said.


Lack of sunlight


The sun is our most significant source of vitamin D, and without it, we quickly become more depressed and irritable. But our “sunlight” doesn’t necessarily need to come from the sun. As long as we have a stable power source, we can use LED lamps that offer safe UV wavelengths allowing us to produce the vitamin D we need. Our crops can benefit from these light sources too! And if that doesn’t work, we can work our way around it by taking supplements or eating fortified foods.


There are also some mental issues related to the lack of sunlight, like Seasonal Affective Disorder (SAD), where people feel more depressed as the days get shorter and there’s less sunlight exposure during the day. Fortunately, there are already some tools in the market that can help you cope with SAD, like therapy lamps that provide artificial sunlight.


Underground living in the present


Many important parts of our daily lives exist “buried” under the ground, like power, information net works, water, sewage pipes, basements, tunnels, and subway systems. However, in some places, you can already find people who actually live underground.


Coober Pedy, a small town just north of Adelaide, in South Australia, is pretty much inhospitable. Temperatures can reach 50ºC, but that didn’t drive the residents away. It drove them down.


Singapore, one of the most populated countries globally, is considering building an Underground Science City (USC). This subterranean science community (40 caverns of labs and data centers) would be made about 80 meters below the surface of Kent Ridge Park and could potentially house over 4 thousand researchers.


In the case of a total planetary catastrophe, things would be a lot different because there could be the possibility of never being able to leave. That scenario would require us to implement new power sources, food, water, and overall living. Depending on the time we had to plan, a lot of luck would also come into play.

Slovak skier Vlhova repeats slalom double in Levi******

BRATISLAVA, Nov. 22 (Xinhua) -- Slovak alpine skier Petra Vlhova repeated her stellar performance from last year and won both slalom races in the Finnish resort of Levi, tying US star Mikaela Shiffrin for first place in the FIS World Cup standings on Sunday.。

Identical to Saturday, Shiffrin placed second, trailing by 0.47 seconds, while German Lena Duerr finished third with 0.78 seconds more on the clock.。

The 26-year-old Vlhova produced four perfect runs and a deja vu-like performance, taking home a double win in the two opening slalom races, exactly like a year before.。

With five victories in Levi under her belt, she became the most successful skier to ever compete there.。

"I feel like my slalom performance is different. I made changes to my team, I have a new coach Mauro Pini and it shows on the track. I am more satisfied and happy. I feel physically stronger," explained Vlhova after the superb weekend.。

The podium looked the same as on Saturday with Shiffrin on second and the biggest surprise of the season Lena Duerr of Germany in third.。

Vlhova was gifted another reindeer calf by the organizers, her fifth overall. "I will probably start a reindeer farm soon. I will call this one Boris after my brother who is a great support, always with me at the start," she said.。

The next event on the schedule is the Giant Slalom in Killington, the United States. Enditem。
