Marine scientist Matthew Huelsenbeck said last week that climate change could see Australia's Great Barrier Reef become extinct within this generation.
His comments came alongside two studies which show further damning proof that man-made climate change is contributing to the fast decline of marine life all over the world.
Half of the Great Barrier Reef has been wiped out since 1955 and the remaining reef is in serious danger, according to a study published by the National Academy of Sciences Journal. Research from the University of British Colombia also found that global warming will cause fish to shrink by up to 25 per cent by 2050.
Dr Huelsenbeck said shrinking fish size and stocks will have "very significant" implications for the poorest of fishermen "who live very close to the shore and can't chase fish all around the world. It's a serious food security issue."
