  • Antibiotic Pollution from the Manufacturing Process

    Why in the News?

    The World Health Organization (WHO) released its first-ever global guidance on managing antibiotic pollution from manufacturing processes.

    What is Antibiotic Pollution?

    • Antibiotic pollution refers to the contamination of natural environments, particularly water and soil, by antibiotics.
    • This pollution occurs when antibiotics are released into ecosystems through various sources, leading to the proliferation of antimicrobial resistance (AMR).
    • AMR happens when bacteria, viruses, fungi, and parasites evolve to resist the effects of antibiotics, making infections harder to treat and posing a significant threat to global health.

    How does Antibiotic Pollution occur from the Manufacturing Process?

    • Wastewater Discharge: Antibiotic plants release wastewater with residual antibiotics and active pharmaceutical ingredients (APIs) into local water bodies, contributing to drug-resistant bacteria.
    • Improper Solid Waste Disposal: Unused antibiotics, raw materials, and by-products are often disposed of improperly, contaminating soil and groundwater.
    • Inadequate Treatment: Many facilities lack effective systems to treat pharmaceutical waste, allowing antibiotics to enter the environment.
    • Mass Balance Calculations: Inefficient systems or mismanagement can lead to unintentional antibiotic discharge during recycling and waste estimation.
    • Leaks and Spills: Accidental leaks or spills during manufacturing, transportation, or storage introduce antibiotics into ecosystems.
    • Runoff: Rainwater can carry antibiotics from waste into nearby rivers, lakes, or agricultural land, further contaminating the environment.

    About Methane Emissions:

    Details
    Nature Colorless, Odourless.

  • Chile’s Atacama Salt Flat sinking due to Lithium Mining

    Why in the News?

    • A recent study published in journal IEEE Transactions on Geoscience and Remote Sensing has found that Chile’s Atacama salt flat (Salar de Atacama) is sinking at a rate of 1 to 2 centimetres per year due to lithium brine extraction.
      • Lithium brine extraction involves pumping salt-rich water to the surface and letting it evaporate in ponds to collect lithium.

    About Salar de Atacama  

    • The Salar de Atacama in Chile boasts the highest lithium concentration (0.15% by weight) among all brine sources worldwide.
    • Argentina boasts more than half of the world’s total lithium resources.
    • It holds the distinction of having the 2nd-largest lithium resources, the 3rd-largest lithium reserves, and the 4th-largest lithium production in the world.
    • It is a part of the Lithium Triangle comprising of Uyuni (Bolivia) and Hombre Muerto (Argentina).

    Key Findings of the Study:

    • Researchers analyzed satellite data from 2020 to 2023 to observe deformations in the Earth’s crust in the salt flat.
    • The area experiencing subsidence measures approximately 8 km north to south and 5 km east to west.
    • The study indicates that subsidence occurs because the rate of lithium brine pumping is faster than the recharge rate of aquifers, leading to the ground sinking.

    What is Lithium?

    • Lithium is an alkali metal, often referred to as ‘white gold’ due to its value and color.
    • It is a soft, silvery-white metal, and notably, it is the lightest metal on the periodic table.
    • It is typically found in various minerals like spodumene, petalite, and lepidolite, from which it is extracted and refined.
    • The leading producers of lithium are Australia, Chile, China, and Argentina.

    Effects of Lithium Mining on Environment:

    • Water Use: Lithium mining, especially from salt flats and brine pools, requires substantial water usage, which can deplete local water resources in arid areas.
    • Ecological Disruption: The extraction process can alter the chemical balance of the natural environment, affecting local flora and fauna.
    • Pollution: Mining and processing lithium can release harmful chemicals into the environment, impacting air and water quality.

    PYQ:

    [2008] Which one of the following pairs of metals constitutes the lightest metal and the heaviest metal, respectively?

    (a) Lithium and mercury

    (b) Lithium and osmium

    (c) Aluminium and osmium

    (d) Aluminium and mercury

  • Why has Malaysia tweaked its ‘Orangutan Diplomacy’?

    Why in the News?

    Malaysia, after initially introducing its version of soft power called “Orangutan Diplomacy” following China’s successful “panda diplomacy,” has now reversed its decision.

    What is Orangutan Diplomacy?

    • It is a Malaysian strategy that seeks to use orangutan conservation as a tool of soft power, inspired by China’s “panda diplomacy.”
    • It had first announced plans to gift orangutans (IUCN Status: Critically Endangered) to palm oil-buying countries.
    • It engages other countries in conservation efforts, focusing on symbolic adoptions rather than sending animals abroad.
    • Reasons behind:
      • Palm Oil Industry Criticism: Malaysia faces criticism for deforestation due to palm oil plantations, threatening orangutans.
      • Enhance Image: It aims to counter negative perceptions and showcase commitment to sustainability and position Malaysia as a leader in wildlife protection.
      • Global Cooperation: It seeks to strengthen ties with major palm oil importers like China, India, and the EU through conservation partnerships.

    Criticisms:

    • Habitat Concerns: Critics argue real conservation requires protecting habitats, not just symbolic actions.
    • Comparisons to Panda Diplomacy: Malaysia’s effort lacks the infrastructure and commitment seen in China’s panda conservation.

    PYQ:

    [2021] With reference to ‘palm oil’, consider the following statements :​

    1. The palm oil tree is native to Southeast Asia.​

    2. The palm oil is a raw material for some industries producing lipstick and perfumes.​

    3. The palm oil can be used to produce biodiesel.​

    Which of the statements given above are correct?​

    (a) 1 and 2 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

  • [pib] Schedule IV of the Wild Life (Protection) Act, 1972

    Why in the News?

    • Many individuals, organizations, and zoos in India currently possess living specimens of exotic animal species listed under Schedule IV of the Wild Life (Protection) Act, 1972.
      • These exotic species must be reported and registered as mandated by the Ministry of Environment, Forest and Climate Change in the PARIVESH 2.0 Portal.

    Legal Framework for Reporting of Animals in Possession

    • The Living Animal Species (Reporting and Registration) Rules, 2024, were notified under Section 49 M of the Wild Life (Protection) Act via a Gazette Notification on February 28, 2024.
    • Who Must Register: Any person or entity in possession of a living specimen of species listed in Schedule IV of the Wild Life (Protection) Act, 1972.
      • Failure to report and register these species within the stipulated time frame may result in penal actions.

    About Schedule IV of the WPA

    Details
    Protection Level Provides legal protection to species, prohibiting their hunting, capture, or trade. Protection is less stringent compared to Schedules I & II.
    Offenses and Penalties Violations can lead to fines and imprisonment, but penalties are generally less severe than those for species in higher schedules.
    New Amendment (2022) The Wildlife (Protection) Amendment Act, 2022, inserted a new Schedule IV for specimens listed in the CITES Appendices.
    Examples of Species Flamingos, Hares, Falcons, Kingfishers, Magpie, and Horseshoe Crabs.
    Purpose Ensures legal protection to prevent exploitation and population decline of species that are not critically endangered but still need protection.
    General Protection Role Plays an important role in broader conservation efforts, offering safeguards to a wider range of species in India.

     

    PYQ:

    [2020] If a particular plant species is placed under Schedule VI of The Wildlife Protection Act, 1972, what is the implication?

  • Yaks from China stray into eastern Ladakh

    Why in the News?

    Around 40 Chinese yaks ventured into Indian Territory in the “Demchok” area of eastern Ladakh and are currently under the control of the local villagers.

    Grazing land issue at LAC:

    • Nomads from both sides traditionally access grazing grounds across the LAC.
    • Indian nomads have been stopped by Chinese soldiers when crossing to the Chinese side.
    • Demchok nomads lost access to Lungkar Valley in 2022 and Nilung Valley in 2017.
    • Loss of these areas has negatively impacted the livelihoods of border residents.
    • China expanded its presence on the Indian side of Charding nala (adjacent to Demchok) since 2020 stand-off.
