Scientists just figured out how to turn minerals from seawater into a carbon-negative building material for concrete! Not only does this process suck more CO2 out of the air than it emits, but it could also replace the need for sand and gravel mining (which is a huge environmental headache). Imagine future buildings literally helping fight climate change—plus, no more wrecking riverbeds for sand. Would you live in a house made from ocean minerals? #ClimateInnovation #SustainableBuilding #ScienceNews #GreenTech #Science
