Climate changes have always had a fantastic influence on the evolution and development of the environment and unfortunately, a lot of times it can modify the way how live beings grow and go through life. Marine scientists have made a new study about the ocean acidification, which is a live fact. The US coastal communities are advised to start preparing for such problems: southern New England, the Pacific Northwest, coastal Alaska and parts of Maine are the problematic regions that suffer from this situation. The communities and the businesses that rely on these foods are a lot to handle and they will have to be ready to confront this unfortunate event. However, it is not related only to the climate, but also to the ocean chemistry that is also changing. Also, social and economic factors, in close relation with pollution and natural processes that happen in the ocean are all sources of acidification.
Nature Climate Change has published this study on Monday.
The main problem that should concern human kind is the extra carbon dioxide that humans are adding in the air through all their day by day activities such as using their cars, agribusiness and so on. Of all that carbon dioxide, more than 25 percent of it goes into the ocean and makes is more acidic. The acidity doesn’t come as much of a help for the carbonate that is very important for the shellfish and coral to grow. As a matter of fact, shellfish need the carbonate to live, and the ocean acidification refuses them constantly.
The response to the people that leave around those areas show how much they depend on the shellfish and how ready they are to make the needed changes for this situation to improve. There is more than $1 billion in revenue going to the coastal communities in the US where the basis of earning a living is the mollusk-fishing.
Lisa Suatoni is a senior scientist for Natural Resources Defense Council and has contributed to the study.
“The conventional wisdom has been to think of vulnerability to ocean acidification only in terms of ocean chemistry. We wanted to fold in a few other dimensions, particularly socioeconomic dimensions, to fill out that picture.”
She explains that by doing so, many more communities are found to be more vulnerable to ocean acidification that previously thought.
16 out of 23 coastal regions in the US have been affected by the ocean acidification level that has grown so much in the recent past. Suatoni says that for shellfish, the most important fact is having those two essential days to build their shell or else they starve.
