Oceans play a crucial role in slowing down the process of global warming, currently by absorbing about half of the CO2 released into the air by human activity every year. Doing so, however, dramatically increases marine acidity and threatens ecosystems.
Advocates of the Cquestrate project insist that the added lime produced from heating limestone will not only boost the amount of CO2 absorbed, but will also reduce the water’s acidity. If the technique were employed on a large enough scale, proponents argue that it would be possible to return global carbon dioxide levels to their pre-Industrial Revolution amounts. The project’s founder Tim Kruger said:
It is essential that we reduce our emissions, but that may not be enough. We need a plan B to actually reduce the amount of CO2 in the atmosphere.
