The higher acid levels in sea waters associated with increased absorption of climate change-related CO2 have long been understood by scientists. However, while it was also known that the survival of organisms with calcium-based shells can be threatened, there had been no known effect on fish.
However, researchers in two separate studies, one in the US and one in Europe, have found that increased CO2 concentrations of 1,000 parts per cubic meter, which are forecast by the end of this century, caused 70% of fish larvae to perish within a week due to organ damage, with those that did live being much smaller than
their normal counterparts.
The scientists concluded that although it had been assumed that the inborn acid-base regulation of fish would protect them from the effects of higher CO2 levels, the eggs and young larvae are extremely vulnerable to these conditions.
Although disturbed by the findings, we are grateful for this information, international scientists. May such insights motivate us all toward actions to preserve all life in the oceans and on Earth.
Speaking during an interview published in The Irish Dog Journal in December 2009, Supreme Master Ching Hai addressed the alarming dangers of climate change such as ocean acidification, as she also spoke of the surest way to restore the balance of the ecosphere.
