Its just a thought.. I figure it will be impractical to isolate effluents from the atmosphere and then pump them underwater (The pumping may be impractical by itself but lets ignore for that now) But what if this process can be carried out at source? What if industries, refineries and power stations can directly send the effluents to the ocean floor? (Industries contribute most to air pollution after all)
Dissolving these gases in water may cause acidification, but how much? i.e what is the safe limit to how much pollutants can be taken care of this way without affecting the conditions of water too much? I understand calculating that accurately is a mammoth task. But lets give it a shot..
1. Lets say we can capture ALL industrial gaseous effluents and disperse them at 450 different sites on the ocean floor. (450 is the number of offshore oil rigs as of today. So I figured if we can build x number of oil rigs, we can build x number of these 'underwater exhaust pipes'.. You can take this number into account for calculations, if you think its necessary) 2. Lets say these dispersion sites are not situated directly at ocean pockets with rich life, but fairly away from them. So there is less damage to aquatic life due to concentrated effluents.
3. Taking into account the volume of water and the volume of effluents, what do you think will be the impact of such a process, roughly?Considerable impact? Moderate Impact? Little Impact? Or negligible impact?
Or is the problem still too complicated to arrive at such a result?
