So there’s global warming. Greenhouse gases, such as carbon dioxide (CO2), contribute to this climate crisis. We must reduce the amount of carbon dioxide in the atmosphere. Nature uses CO2 as a building block. Hard coral types turn it into limestone.
Factories have been built that mimic these coral’s formula. They extract CO2 from the air and turn it into limestone, which can be used for concrete in roads and buildings.
Normally concrete is responsible for 8% of the global yearly CO2 emitted
This solution is a two-way street. First the level of CO2 in the atmosphere is reduced. Second, there’s just a fraction of the CO2 emitted that usually is the case when producing concrete.
