There are numerous other issues raised that relate to global warming. One of them is the acidification of the ocean (ocean acidification) adding co2 in the atmosphere increases the co2 dissolved in seawater Which makes the ocean more acidic. Studies estimate that the ph at the sea surface when the industry started with the 8.25 and dropped to 8.14 in 2547 [98] estimated that the ph will drop at least 0.14 to 0.5 units by the year2643 as the ocean absorbs more co2 [1] [99] However, microbial organisms and ecosystems to exist in a narrow range, ph, this phenomenon may cause extinction. As a direct result of increasing the amount of co2 in the atmosphere.Which may directly affect human societies that depend on marine ecosystems is great.
