A study published in Science believes that if ozone depletion,caused mainly by CFC gases, will not be controlled and reduced, he global
temperature will rise 4.3 degrees above the pre-industrial level, leading to the disappearance of 16% of the entire flora and fauna of the planet by 2100.
I photographed, for a year in the Ticino park, spontaneous plants and flowers, using as a filter caps of spray cans pierced by a flame, each
time a different one.
It was symbolically as if I were looking through the ozone hole.
