Concrete is a huge polluter, but a scientist in New Zealand is shaking things up by using ancient Roman tricks—think volcanic ash and seashells—to make eco-friendly, self-healing concrete. This new mix could slash carbon emissions, cut costs, and even fix its own cracks over time. Imagine cheaper, greener buildings that last for centuries! Would you trust ancient wisdom to build your next home? #Science #EcoInnovation #SustainableLiving
