Ocean acidification pertains to a decrease in the ocean’s pH over a prolonged period of time, triggered mainly by the uptake of carbon dioxide (CO2) from the atmosphere.
For over two hundred years, or perhaps from the industrial revolution, the level of carbon dioxide (CO2) in the atmosphere has multiplied as a result of the combustion of fossil fuels as well as the land utilization change. The sea absorbs as much as 30% of the CO2 being emitted in the atmosphere, and just as levels of atmospheric CO2 maximize, the levels in the ocean do the same too.
Once CO2 is assimilated by seawater, multiple chemical reactions take place leading to increased concentration of the hydrogen ions. This increase stimulates the seawater to become even more acidic and triggers carbonate ions to be comparatively less abundant.
These modifications in ocean chemistry can impact the behaviors of non-calcifying organisms too. Particular fish’s ability to sense predators is decreased in extra acidic waters. As soon as these organisms are in danger, the entire food web is likewise at risk.
Ocean acidification is upsetting the entire world’s ocean waters, along with coastal estuaries and waterways. Most economies are relying on fish and shellfish and people all over the world depend on foods from the ocean to be their main source of protein.
