London is the latest city to gain a city bench with the ability to absorb as much pollution as a small forest. The vertical garden, which doubles as a bench, is Green City Solutions’ CityTree. Using a vertical installation of moss, the bench can absorb as much pollution as 275 trees in 1 percent of the space.

The World Health Organization estimates that 7 million premature deaths occur each year from air pollution, making it one of the largest environmental health risks in the world.
