DYWO is a digital project that shows in the form of a real-time visualization the collective suicide that humanity is committing through the destruction of its ecosphere. Each black spot represents a zone of more or less important emission of nitrogen dioxide (NO2), one of the most toxic pollutants emitted by human activity. For each emission area, the sources of the pollution and their locations appear to the right of the main circle. The data are based on daily analyses from Copernicus and historical data from NASA.
