Shopping centers underground

Huge metropolises like Singapore or Hong Kong have already started to change their laws to allow universities, libraries, cinemas or shopping malls to settle underground. And trees planted on land reclaimed from concrete or tarmac are all contributions, however small they may be, to the fight against air pollution.

Sheltering underground can also allow the population to protect themselves from severe weather, such as cyclones, feared by global warming. "Faced with floods and other natural disasters, this can really make the city more resistant, if we exploit its underground potential," said this expert. "Optical fiber can bring light underground and today it is possible to simulate a brightness specific to natural light," she says. The survival of plants without the sun's rays is at the center of many studies, which seek in particular the optimal frequency on the light spectrum to allow photosynthesis, essential for plant growth.
