The Green Tech Bringing Life Back to the Sea

The video discusses the negative impact of traditional concrete on marine life and introduces an innovative solution by an Israeli startup, E Concrete. This company develops special cement formulas that enhance marine biodiversity by creating hospitable habitats for marine organisms. The concrete is designed to mimic natural environments, promoting the growth of marine flora and fauna. The video highlights the economic and environmental benefits of this technology, including reduced maintenance costs and carbon footprint, while enhancing the structural integrity of marine constructions.

What is a negative consequence of clear water around seawalls?

• It indicates a healthy marine ecosystem.
