Polluted sky by industry at dusk, can be considered a picture that denounces the mistreatment of humans by the planet. It is part of a series dedicated to the skies in all its facets, storms, rains, pollution, and sunrises, showing the multiple shades that nature offers us in the sunsets, and skies illuminated by the spills of the factories. In this series, I try to show all possible scenes using a demanding colour palette to achieve the goal I set for myself.
