Scientists have found yet another likely reason why the world should dramatically cut its greenhouse gas emissions.
Global warming could disrupt four-fifths of the world's ocean ecosystems by 2050 if emissions keep climbing, threatening the main food source — fish — of about one in seven people globally, a new study found.
As ocean temperatures rise, and as waters absorb more carbon and turn acidic, marine life will struggle to adapt and may decline or die-off, according to research published Tuesday in the journal Nature.
On a slightly brighter note, however, reducing emissions would tangibly benefit organisms by giving them more time to adapt. Plant or coral species may develop heat-resistant characteristics, while schools of fish could build migrate to cooler waters near the Earth's poles.
