For example, acid rain from vehicle emissions and industry cause an increase in ocean acidity, which is likely relevant, at least near urbanised regions \cite{Doney_2007}. Additions of organic carbon to the ocean, such as sewage, decomposes to dissolved inorganic carbon (DIC), and increases acidity \cite{Nagelkerken_2015}. Agricultural run-off provides nutrients which then fuel (an anthropogenic) increase in production of organic carbon in the ocean\cite{Howarth_2002}, again increasing acidity.'' To correctly measure OA DIC, pH, total alkalinity (TA), and partial pressure of CO2 (PCO2 )— must be known, in addition to temperature and salinity and to be more accurate, phosphate and silicic acid concentrations are also required \cite{Haigh_2015}.'' OA affects the ecosystem mostly by the disruption of the food web chains. As an example, in areas like British Columbia where the class of diatom Phytoplankton (which has an higher trophic transfer) is predominant \cite{Ryther_1969}, a switch to a class with lower nutritional value would take place affecting the directly the higher trophic levels\cite{Haigh_2015}.
