Architects in Italy are designing skyscrapers with trees on each floor, to the top floor. Why? To reduce heating and cooling costs, clean the air, conserve energy, filter dust and, while absorbing carbon dioxide, produce oxygen. They are aesthetically pleasing as well.
Will it work?
"They are pioneers, new neighbours being asked to live with us in the sky. They'll take in the CO2 and breathe out oxygen. We'll take in the oxygen and breathe out CO2. We'll water them. They'll aerate us. It's a whole new neighbourhood. Yes, we may stumble as we rise, but rise we shall. These towers in Milan will lead the way." (Robert Krulwich is quoted as saying in the article which may be accessed through the link above.)
Do you think it will work? My questions are: where will they put the dirt within which the trees will be planted and how much do they need to sustain the life of the tree? Can the structure support this weight?
Do you think this is a feasible project?
