The age of green is upon us. We have reached a point in our human evolution where science, math, and creative genius have discovered a way to suspend a living forest in mid air. The answer to city pollution is now Stefano Boeri’s Bosco Verticale, the world’s first 27-story microclimate apartment towers currently under construction in Milan, Italy. Built to function as city air purifiers, these lush apartments will include over 900 trees, 5,000 bushes, and 11,000 plants throughout the tower balconies. Each perch of life will aid in reducing city noise, moderating atmospheric temperatures, absorbing CO2 emissions, and acting as an energy sustainer for seasonal weather shifts.
