How can ocean acidification be reduced
WebOcean acidification is a global threat with potential impacts on marine food webs, ecosystem productivity, commercial fisheries and global food security. This threat has prompted the international scientific community, including Fisheries and Oceans Canada, to investigate the implications of this significant international governance issue. WebOcean acidification is the decrease in the pH of the Earth’s ocean.Between 1950 and 2024, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO 2) levels exceeding 410 ppm (in 2024). CO 2 from the …

WebOcean acidification contributed to reduced growth for white seabream and Senegalese sole and a small increase for zebra seabream, as well as a decrease in egg production of 48–52% and 14–33% for white seabream and Senegalese sole, respectively, and an increase of 4–5% for zebra seabream. WebDr. Ellen Thomas, Senior Research Scientist in the Department of Earth and Planetary Sciences, further explains that the ocean is not turning into acid, per say. Instead, it is just becoming less basic. “Remember the pH scale from elementary school,” Thomas says. “There is a number seven in the middle. Everything lower than 7 is acid, and ...

Such negative ... WebOcean acidification can negatively affect marine life as it causes shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean, the faster the shells dissolve. Animals that produce calcium carbonate structures have to spend extra energy repairing or thickening their shells, which could impact their ability to grow and reproduce.
