What is interesting for Carlos is how the progress of light technology allows humans to ‘colonise’ the night. Sometimes, this illumination serves to double the hours for work and pleasure. But this affects both animals and man for better and for worse. Urban lighting is undergoing a revolution alongside landscape development and trends. The most obvious advantage lies in the greater sense of security evoked by a well-lit environment. The lights ease movements during the night, making it safe and reassuring.

However, Carlos’s research also points to the fact that light pollution can lead to serious and irreversible impacts on humans, plants and animals. From retinal damage and skin cancer to sleep disruptions and increased carbon emissions, excessive use of lights can trigger a myriad of harmful effects. Yet, as Carlos spending time observing different cities, he also grows more aware of how its inhabitants are oblivious to the way they are put at risk when exposed to the lights.
