A new study by scientists into the future effects of acidic sea water shows that the reduced pH value of the oceans’ surface waters will have drastic results in around 100 years’ time. The scientists, from Sweden and Australia, carried out the world’s first research into how a lowered pH of the sea’s surface water affects marine animal life. In their project, they allowed sea urchins of the species Heliocidaris Erythrogramma to fertilize themselves in water where the pH has been lowered from its normal 8.1 to a pH value of 7.7. This means an environment three times as acidic, and corresponds to the change expected by the year 2100.
