"Without water there is no life and with rising temperatures we are exposed to drought on the one hand and floods on the other," they added. "We have tough years ahead of us, but if we don't get to zero emissions immediately, they will be terrible." Photos captured activists in orange vests standing waist-deep in the fountain. They unfurled orange banners that read in Italian: "Our future is as black as this water" as crowds of onlookers took pictures.
