How biowalls improve well-being

摘要

We are gradually understanding the need to improve our environment. Wind turbines, like them or not, are multiplying, and solar panels with their big brothers, solar walls and solar roofs are helping to produce "green" energy. Green roofs covered with closely packed plants growing in a few inches of soil on a waterproof layer in place of roof tiles help to insulate buildings, collect rainwater and reduce air pollution. The use of biowalls to absorb air pollution has not so far become widespread but some research into their possibilities is going on. We are unlikely to see whole skyscrapers covered with plants but small scale indoor biowalls have been used, if only to enhance the appearance of some office developments.
