PROBLEM TO BE SOLVED: To reduce carbon dioxide increased in the open air. SOLUTION: A seawater pumping-up step supplying the power from a solar cell panel 4 to a pump 1 and a jet nozzle 3 and using the pump 1 and a piping 2 to pump up seawater to the jet nozzle 3 from a deep place, a seawater sprinkling step for sprinkling pumped-up seawater over the surface of the sea from above by using the jet nozzle, a step for measuring the amt. of CO2 contained in pumped-up seawater by using a seawater CO2 content measuring device, a step for measuring the amt. of CO2 contained in sprinkled seawater by using the seawater CO2 content measuring device 6 and an absorbed CO2 amt. calculating step for subtracting the CO2 amt. in sprinkled seawater from the CO2 amt. in pumped-up seawater to calculate the CO2 amt. taken in seawater by using an absorbed CO2 amt. calculating sensor 8 are provided.
