Remark:
Has any impact study been done on the carbon dioxide storage underground? While this sounds like a great idea in slowing down global warming, I am concerned that this will lead to environmental, ecological and geological disasters. How is the storage reservoir constructed, and with what material? When carbon dioxide is dissolved in water, it forms carbonic acid. The destructive effect of carbonic acid, generally known by the public as acid rain, is evident in many sculptures, monuments and buildings. In higher concentration, carbonic acid can change the pH of the soil, which may probably destroy organisms living in the soil. If carbon dioxide is to be stored in compressed form, the pressure may cause instability in the soil structure, and may even create man-made volcanic eruption one day.
