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.

The '30x30' target, a key component of the Kunming-Montreal Global Biodiversity Framework, aims to effectively conserve and manage at least 30% of the world's land and sea areas by 2030.

Habitat loss and degradation, driven by land-use change, agriculture, and urbanization, is consistently identified by UNEP and other scientific bodies as the leading direct driver of biodiversity loss.

The Kunming-Montreal Global Biodiversity Framework (GBF) was adopted at COP15 in December 2022, setting ambitious goals and targets for 2030 and beyond, replacing the Aichi Targets. UNEP reports often assess progress towards such frameworks.

DRDO successfully conducted the test of the new generation Anti-Tank Guided Missile in March 2026, bolstering India's indigenous defense capabilities.

The new generation ATGM tested by DRDO boasts an extended range and an advanced guidance system, making it more effective against modern armored threats.
