http://www.independent.co.uk The burning of fossil fuels releases 11 BILLION TONS of carbon dioxide into the atmosphere every year. http://www.babble.com

Carbon dioxide dissolves in the ocean, where it causes a potentially more serious problem  ocean acidification. Hoegh-Gulderg et al. 2007

Ocean acidification poses a threat to shell-forming organisms like corals and calcifying plankton. www.greendiary.com http://elrid.cult.bg
