Polluted air is the cause of one in seven deaths worldwide. And the air pollution in cities is the worst. Trees help. But you need a lot of trees to clean the air in congested cities. That’s where City Tree comes in. This mix of a bench and a hedge cleans as much air as 275 trees in one percent of the space. You can find City Trees in Berlin, Paris, Amsterdam, Oslo and London.
