A group of European scientists propose that we could all live in gigantic fungus buildings. An entire city, from apartments, schools and stores to the hospitals would be made of living fungus – constantly growing, dying off and regenerating itself. That's the vision laid out in a provocative new paper, reported by Dan Robitzski in Futurism since the paper has not yet been peer reviewed. The idea is in response to the prospect of catastrophic climate change. Growing our building materials from biological materials, the theory goes, would make construction less dependent on fossil fuels and environmentally destructive mining operations.
