OCEANS COULD BE USED TO SLURP UP CO2?

American researchers have proposed a method, reported in Science Daily, of using and enhancing the ocean's absorption of carbon-dioxide by building many hundreds of water-treatment plants round the world. They would extract hydrochloric acid from seawater, which would be neutralised with rock. That would make the oceans more alkaline, enhancing their ability to soak up more CO2. They say 700 plants would offset all our carbon-dioxide emissions.
