There's many physiological processes that are influenced by the acidity of the ocean.

Think about bittersweet chocolate or think about the acidity of yogurt wonderful mixed with strawberry fruits.

I remember her gay charm when she had achieved her own way over something... and her extreme acidity when she didn't.

The amount of nitrogen and sulfur circulating through the Earth system has doubled. The ocean s pH is changing at an unprecedented rate, reaching levels of acidity that marine organisms have not experienced in the last 20 million years.

GAW serves as an early warning system to detect further changes in atmospheric concentrations of greenhouse gases, changes in the ozone layer and in the long range transport of pollutants, including acidity and toxicity of precipitation as well as of atmospheric burden of aerosols (dirt and dust particles).

The studies, observing the complexity of the interactions between living organisms and the chemistry of their aquatic habitats, note that the ecosystem of the entire water body may be affected through the predator prey relationships of the food web and that species of plants and animals may decline or disappear as acidity increases.
