1. On 15th August 2024, the Ministry of Defence will lead a significant tree plantation drive, aiming to plant 1.5 million trees across India. This initiative, part of the 'Ek Ped Maa Ke Naam' campaign launched by the Prime Minister on World Environment Day 2024, is dedicated to honoring mothers. The campaign will be executed by the three Services, Defence Research and Development Organisation (DRDO), Defence PSUs, Controller General Defence Accounts (CGDA), National Cadet Corps (NCC), Sainik Schools, and Ordnance factories. The drive highlights a commitment to environmental conservation and tribute to motherhood.
2. International Tiger Day, observed on 29th July, aims to raise awareness about the endangered tiger and the global efforts to protect it. Established in 2010 at the Saint Petersburg Tiger Summit, the day highlights the TX2 goal, an initiative by the World Wildlife Fund (WWF) to double the wild tiger population by 2022. This goal is supported by 13 tiger range countries and various organizations like the Global Tiger Initiative and Global Tiger Forum. The focus is on enhancing wildlife protection by expanding protected areas, promoting sustainable livelihoods, and preserving forests in tiger habitats.
3. Scientists have recently identified a new source of oxygen in the abyssal zone, termed ‘dark oxygen,’ where photosynthesis is not possible due to the lack of sunlight. This discovery, observed in the Clarion-Clipperton Zone off Mexico’s west coast, suggests an unknown process might be generating oxygen, possibly involving polymetallic nodules that transport electric charges to split water molecules. Deep-sea mining, which includes extracting these nodules, seafloor sulfides, and cobalt crusts, is rising in importance due to valuable materials like nickel and cobalt. However, environmental concerns arise as deep-sea mining could damage ecosystems reliant on this newly discovered oxygen source. In India, deep-sea exploration is expanding with efforts to explore minerals beyond its jurisdiction and the development of the Samudrayaan Mission for resource extraction.

4. A recent Nature Communications study reveals that weakened ocean circulation might increase atmospheric CO2 levels, challenging previous assumptions. Ocean overturning circulation, which moves water and nutrients globally, traditionally was thought to balance carbon storage despite weaker circulation. However, the study finds that reduced circulation could disrupt complex feedback mechanisms involving iron, microorganisms, and ligands—organic molecules that influence iron availability for phytoplankton. This disruption may lead to increased atmospheric CO2 by undermining the ocean's carbon sink effectiveness. The findings stress the need to reevaluate the ocean's role in climate change mitigation, as reduced circulation could exacerbate global warming by decreasing the ocean's capacity to sequester carbon.
