More than half of humanity is currently living in cities – with numbers growing. If cities were the living space of the future – wouldn’t it be nice to integrate nature?
Air is our most important resource within the cities; however it is often so polluted, that breathing will actually harm our health. Green City Solutions is working on a future, in which fresh air in urban areas is available to everyone. For that reason, they have developed the world’s first bio-tech filter for quantifiably better air quality: The CityTree.
