Even organisms that deal with short-term changes in acidity, may suffer if the condition persists.


I have often wrote about the fact that carbon dioxide emissions cause climate change, and it contributes to global warming. Often overlooked, however, is another, no less important problem associated with air pollution including gas. As many as 25% of the CO2 emitted is in fact absorbed by the oceans. This slow process, lasting decades, causes an increase in the acidity of ocean waters, and thus the change in the prevailing conditions by acidification. liqui moly
The pH level of ocean water is relatively well documented, so we know that currently amounts to an average of 8.1, whereas prior to the start of the industrial revolution it was around 8.2. This difference seems small, but you have to remember that the pH scale is logarithmic, which means that at that time the acidity has increased by approximately 30%. It is estimated that by the end of the century it will be even 7.8.
Acidification of the oceans affects the chemical composition of the water, by which organisms living in this environment must devote increasing amounts of energy to maintain the proper proportions of individual ions inside their bodies. Particularly sensitive to such fluctuations are clams, corals and some snails. Very important for them is the availability of carbonate ions, so that build their skeleton or shells. However acids bind these ions, and hence their availability decreases.
Even organisms that deal with short-term changes in acidity, may suffer if the condition persists. Besides, if acidification is not the only problem, and the inhabitants of the waters must contend with other adverse liqui moly factors, their chance of adaptation and survival is proportionately lower. Works to their disadvantage is the fact that the self-return to the optimal pH of the environment is so slow that it is not balanced by progressive acidification, which is now faster than ever.
Thus increasing acidification can cause a slow extinction of aquatic species or replacing liqui moly some other - more robust liqui moly to adverse conditions. Usually, however, this situation represents a decrease in biodiversity and disturbance of the natural balance in the environment. The consequences and can be difficult to predict.
At the pH of ocean water is affected, of course, other factors, such as fertilizer runoff from agricultural fields, or acid rain. In addition to the situation liqui moly in some regions affect ocean currents, liqui moly and the pH in the coastal zones is usually lower than in the open ocean. All these factors may exacerbate local acidification, however, the global remains primarily cause increased carbon dioxide emissions into the atmosphere.
