The release of hydrogen ions (H+) increases the acidity of the water, which is measured as a decrease in pH. A lower pH indicates higher acidity.

Ocean acidification reduces the availability of carbonate ions, which are essential building blocks for the shells and skeletons of calcifying organisms like corals, oysters, clams, and other shellfish.

Ocean acidification is caused by the uptake of excess atmospheric carbon dioxide (CO2) by the oceans, leading to a decrease in seawater pH.

India is a signatory to the Ramsar Convention on Wetlands, an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

Healthy wetlands act as natural filters, purifying water by removing pollutants, and also serve as sponges, absorbing excess water and mitigating floods, thereby providing essential ecosystem services.

The term 'Sanrakshan Abhiyan' (conservation campaign) for 'Amrit Sarovar' (nectar ponds/water bodies) implies a focus on the rejuvenation, protection, and sustainable management of water bodies, which includes wetlands, to enhance their ecological services.
