There being mentioned billions of people within this article and the rarely mentioned, made my hair stick up so to speak. Because there still seeming has been nothing said about growing populations, that will need more food. Will create more pollution, population control seemingly is not on the menu as yet, nor put into scientific calculations.

Acidification of the oceans is a major threat to marine life and humanity's food supply, Hilary Benn is to warn as the UN climate summit resumes.

The UK environment secretary will say that acidification provides a "powerful incentive" to cut carbon emissions.

Ocean chemistry is changing because water absorbs extra CO2 from the air.

Some believe this could be as big an impact of rising CO2 levels as climatic change, though it is rarely discussed within the UN climate convention.

The UN summit in Copenhagen, which started a week ago, is scheduled to conclude on Friday, when more than 100 world leaders will attend in an effort to agree a new global treaty on climate change.

Research on acidification....

Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by their uptake of anthropogenic carbon dioxide from the atmosphere.[1] Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.179 to 8.104 (a change of −0.075).[2][3]
