Ocean Acidification –

Indian Ministry of Earth Sciences defines Ocean acidification as the decrease in the pH level of the ocean over time, caused by the absorption of excess carbon dioxide (CO2) from the atmosphere. This increase in CO2 reacts with water to form carbonic acid, reducing the pH of the ocean and making it more acidic.

Steps taken to overcome Ocean Acidification –

1. Enhancing carbon capture and storage technologies.example -converting carbon dioxide into stable solid minerals through chemical reactions.
2. Transition to low carbon economy .example -Sweden’s carbon tax reduced emissions by 23%.
3. Enhance ocean alkalinity through mineral addition.example-limestone, calcium hydroxide,silicate .
4. Establishment of ocean acidification monitoring networks.example- Indian Ocean Acidification Monitoring (IOAMN).
5. Development of ocean acidification related innovation hubs .example- India’s Ocean Acidification Research and Development Centre (IOARDC).
6. Promote engagement of local communities in marine conservation.example – community led marine protected areas .
7. Organize ocean acidification awareness campaigns.example- Ocean Acidification Day on 8 June .
8. Promote sustainable lifestyle choices.example – zero waste challenge ,eco friendly swaps etc .

Implementing these measures requires collective action from governments, industries, civil society, and individuals to mitigate ocean acidification’s impacts.
