Have you heard of “sponge cities”? Believe it or not, there are cities around the world that are actually being redesigned to soak up rainwater like a sponge, using green roofs, parks, wetlands, and permeable roads. The goal? Reduce flooding, improve water quality, and make our cities more resilient.
