This underwater incarnation of Leandro Erlich's The Reefline project, Concrete Rd, will offer an entirely new reading of the impermanence which will also be imagined and come to life in the corresponding NFT project.  As opposed to the sand cars shown on the beach, these submarine sculptures do not degrade over time. Instead, they will be colonized by life and merge with the natural environment. Our fear of being “underwater” (as a consequence of climate change) will also be transmuted into the generation of new homes for underwater lifeforms and the development of a new marine ecosystem. The structure of these human-made vehicles (a symbol of the climate-changing emissions that endanger our planet) will become new vehicles of environmental change. Concrete Rd's stone sculptures will be silent, engineless, creating new life in our shared waters. The digital version of this work provides a glimpse of what might happen to this installation over time, and the positive effects that this marine sanctuary may come to have on the biodiversity of waters off Miami Beach.
