Steadily increasing levels of seawater acidity could re-shape strategic food chains in the polar and sub-Antarctic marine ecosystems earlier than predicted, according to research published in Nature.
“Within 50 to 100 years, there could be severe consequences for marine calcifying organisms, which build their external skeletal material out of calcium carbonate, the basic building block of limestone,” says Australian scientist, Dr Richard Matear of the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

Stellar processes excepted, carbon is neither created nor destroyed. As an element it enters readily into combinations with other elements but is not destroyed. Its compounds are sometimes broken down or altered but this does not destroy or create carbon. All ordinary chemical processes are carbon neutral.
