The End of Ocean Life

“Every second breath we take comes from marine photosynthesis, a process which also uses 60-90% of our carbon dioxide. If we have lost 50% of the very thing that regulates the climate, surely it is time to stop, take a fresh look at ocean chemistry and biodiversity and ask ourselves some fundamental questions: ‘Why have we lost this level of marine life? Why is the decline continuing? What does this mean for our climate and humanity?’

“Of particular concern from a climate change perspective is the level of carbonic acid in the oceans, which is the result of atmospheric carbon dioxide being dissolved into the oceans. In the 1940’s pH was 8.2, but in 2020, pH had dropped to it 8.04, meaning the ocean is becoming more acidic. If there are no plants to use the ‘carbon’ for photosynthesis, this leaves unused carbonic acid to move the pH downwards. Reports from respected institutes around the globe, flag an acceleration of the ocean acidification process, which will result in the loss of more marine plants and animals, especially those that have carbonate shells and body structures (aragonite) based. These same reports forecast that in 25 years, pH will drop to 7.95 (2045) and with this, they estimate 80% to 90% of all remaining marine life will be lost – that in the GOES team’s opinion is a tipping point; a planetary boundary which must not be exceeded if humanity is to survive.”
