I came across a few different articles and social media post that claim moss is far better at absorbing CO2 and other pollutants then trees. The article from the link below claims that a relatively small planter is the equivalent of 250 trees. Is this accurate? If it is, why isn't this more common?
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.
