Climate change causes seawater acidification to threaten marine species

The number of clams in the ocean is threatened by acidified seawater due to climate change. This is the research result published in the Scientific journal Interface (UK) on 24/12.

Researchers from Glasgow University (Scotland) have experimented with common blue mussels on the ocean.

These boys were put to live in four water environments with different temperatures and pHs, created by scientists based on predictions of the sea environment for the next few decades.

The results showed that the calcium shell enveloping the boys became brittle and more fragile and the aragonite layer on the inside of the shell was also softer when the acid concentration was higher. This means that they will be more easily attacked and more fragile by rivals by the effects of other factors in the ocean environment.

Meanwhile, the increasing amount of carbon dioxide (CO2) emissions into the environment, meeting chemical reaction water producing carbonic acid makes the concentration of acid in the sea higher and higher.

This is a threat to mussels, as well as to the capture fisheries of humans when the catch depends on the number of clams that exist in the ocean.
