Description: Imagine looking out from your 18th floor apartment in the middle of the city and seeing trees right in front of you. In an effort to stem climate change, reduce pollution, combat heat, and protect biodiversity, architects are teaming up with botanists, urban wildlife ecologists, and other scientists to design high-rise forests, living walls, and vertical farms in some of the world’s most populated places. These projects are happening all around the world, and they will not only change the urban landscape, but they will provide urban dwellers with a healthier place to live and work.
