Farming with Silicate Rocks: A Systemic Approach to Carbon Sequestration
Original framing: “Spreading crushed rock on farms could absorb 1 billion tonnes of CO2” — New Scientist
The core of the article rests on scientific reasoning: silicate weathering chemistry, carbon balance calculations, and the agronomic trade‑offs of rock addition. It cites data and methodological concerns, reflecting a strong scientific grounding.
The proposal to spread silicate rocks on farmland sits at the intersection of hard science and systemic risk, revealing that carbon sequestration cannot be isolated from soil ecology, supply chains, and social equity.
While the scientific basis is solid, the absence of Indigenous, artistic, and cross‑cultural lenses narrows the narrative, and the marginalised impacts of mining remain under‑explored. By weaving together regenerative practices, circular waste streams, policy incentives, and community stewardship, a more resilient pathway emerges—one that captures carbon, restores soils, and respects the histories and voices of those most affected.
