The largest cities on Earth are probably partly underground now. But in the future it could be that we will all need to live underground. The surface may become uninhabitable for various reasons, such as global warming, nuclear war or the destruction caused by volcanoes.
Or perhaps it will just make sense to move underground. The temperature is stable and the surface can be used for farming or recreation. It could become fashionable for houses to be built underground. And an underground city would encourage tourists.
Would it be possible for everyone on the planet, say 10 billion people, to live underground? How would we grow plants? Would we be able to keep animals? Would we be able to live without sunlight? Would you enjoy living underground?
Come and discuss underground cities with us. Bring a spade, and some strong friends!
