Fish species are already dieing off because of the increases acidity of bodies of water. T
Really? Where? Scripps found that acidity in the oceans is natural and nothing to be concerned about. I also notice you have studiously ignored the link I provided. I wonder why

Until recently we had very little data about real time changes in ocean pH around the world. Finally autonomous sensors placed in a variety of ecosystems “from tropical to polar, open-ocean to coastal, kelp forest to coral reef” give us the information we needed.
It turns out that far from being a stable pH, spots all over the world are constantly changing. One spot in the ocean varied by an astonishing 1.4 pH units regularly. All our human emissions are projected by models to change the world’s oceans by about 0.3 pH units over the next 90 years, and that’s referred to as “catastrophic”, yet we now know that fish and some calcifying critters adapt naturally to changes far larger than that every year, sometimes in just a month, and in extreme cases, in just a day.
Data was collected by 15 individual SeaFET sensors in seven types of marine habitats. Four sites were fairly stable (1, which includes the open ocean, and also sites 2,3,4) but most of the rest were highly variable (esp site 15 near Italy and 14 near Mexico) . On a monthly scale the pH varies by 0.024 to 1.430 pH units.

The authors draw two conclusions: (1) most non-open ocean sites vary a lot, and (2) and some spots vary so much they reach the “extreme” pH’s forecast for the doomsday future scenarios on a daily (a daily!) basis.
At Puerto Morelos (in Mexico’s easternmost state, on the Yucatán Peninsula) the pH varied as much as 0.3 units per hour due to groundwater springs. Each day the pH bottomed at about 10am, and peaked shortly after sunset. These extreme sites tell us that some marine life can cope with larger, faster swings than the apocalyptic predictions suggest, though of course, no one is suggesting that the entire global ocean would be happy with similar extreme swings.
Even the more stable and vast open ocean is not a fixed pH all year round. Hofmann writes that “Open-water areas (in the Southern Ocean) experience a strong seasonal shift in seawater pH (~0.3–0.5 units) between austral summer and winter.”
This paper is such a game changer, they talk about rewriting the null hypothesis:
“This natural variability has prompted the suggestion that “an appropriate null hypothesis may be, until evidence is obtained to the contrary, that major biogeochemical processes in the oceans other than calcification will not be fundamentally different under future higher CO2/lower pH conditions””
