Another way to get rid of CO2?

On top of all the weird and wonderful mechanisms already proposed, here's the next idea from Science Daily, slurping. This method suggests getting the oceans to slurp up the excess CO2 by removing Hydrochloric acid from sea-water by electrolysis; thereby increasing its alkalinity, which means it can absorb more CO2. They reckon 700 special treatment plants worldwide could offset all CO2 emissions.

It sounds sort of feasible, but surely reducing our emissions, whilst at least trying to halt our population growth, would be more straightforward? We need to tackle the cause, not the consequences.
