    Green Taxonomy is a classification system that defines which economic activities are environmentally sustainable. It serves as a guideline for businesses, investors, and policymakers to direct capital towards projects and industries that contribute to environmental goals such as climate change mitigation, pollution reduction, and biodiversity conservation.

    Key Aspects of Green Taxonomy

    1. Objective-Oriented – It aligns with global sustainability targets, such as the Paris Agreement and the UN Sustainable Development Goals (SDGs).
    2. Scientific Basis – It uses scientific criteria to determine whether an economic activity is environmentally beneficial.
    3. Policy Framework – It provides a foundation for financial regulations, investment strategies, and sustainable finance initiatives.
    4. Avoids Greenwashing – By setting clear definitions, it prevents companies from falsely claiming sustainability.
    5. Sector-Specific Guidance – It applies to various industries, including energy, agriculture, transportation, and manufacturing.

    Notable Green Taxonomies Around the World

    1. EU Taxonomy (European Union) – A leading framework under the European Green Deal, providing detailed criteria for sustainable activities.
    2. China’s Green Bond Endorsed Project Catalogue – Defines green investments for bonds and financial markets.
    3. ASEAN Taxonomy – A regional initiative to guide sustainable finance in Southeast Asia.
    4. India’s Green Taxonomy – Under development to promote sustainable economic activities.
    5. UK Green Taxonomy – A framework similar to the EU’s, tailored for the UK’s climate goals.

    Why is Green Taxonomy Important?

    • Encourages Green Investments – Helps investors and companies identify eco-friendly opportunities.
    • Supports Climate Goals – Aligns economic growth with environmental sustainability.
    • Creates Market Transparency – Establishes standardized criteria for sustainability claims.
    • Reduces Financial Risks – Helps investors assess environmental risks linked to assets.

    Green taxonomies are a crucial tool in achieving a sustainable and low-carbon economy by directing capital towards projects that genuinely benefit the environment.

    Water hyacinth (Eichhornia crassipes) is often considered an invasive aquatic plant, but it also has several ecological benefits. Here are some key ways it contributes positively to the environment:

    1. Water Purification

    • Phytoremediation: Water hyacinth absorbs heavy metals like lead, mercury, and cadmium, helping to detoxify polluted water.
    • Nutrient Absorption: It removes excess nitrogen and phosphorus, reducing eutrophication (algae blooms) in water bodies.
    • Filtration of Contaminants: The plant captures suspended solids and organic pollutants, improving water clarity and quality.

    2. Carbon Sequestration & Oxygen Production

    • Acts as a carbon sink, absorbing CO₂ from the atmosphere.
    • Produces oxygen through photosynthesis, benefiting aquatic life.

    3. Habitat for Aquatic Life

    • Provides shelter for fish, amphibians, and invertebrates.
    • Serves as a breeding ground for certain species, improving biodiversity in some ecosystems.

    4. Soil Enrichment & Erosion Control

    • When decomposed, it adds organic matter to the soil, improving fertility.
    • Prevents soil erosion along riverbanks and wetlands by stabilizing sediments.

    5. Potential Biofuel & Biomass Source

    • Can be used to produce bioethanol, biogas, and compost, reducing reliance on fossil fuels.
    • Helps in sustainable waste management through biomass utilization.

    Despite its ecological benefits, uncontrolled water hyacinth growth can disrupt ecosystems. Proper management and controlled cultivation can help harness its positive attributes while minimizing its negative impacts.

    What is Soil Erosion?

    Soil erosion is the process by which the top layer of soil is removed or displaced by natural forces such as wind, water, ice, or human activities. It involves the wearing away of the fertile, nutrient-rich upper layer of soil, which is essential for plant growth and overall ecosystem health.

    Effects of Soil Erosion on the Biosphere

    Soil erosion significantly impacts the biosphere in various ways:

    EffectDescription
    Loss of Fertile TopsoilThe top layer of soil, rich in nutrients and organic matter, is essential for plant growth. Its loss reduces agricultural productivity and affects plant life.
    Reduction in Agricultural YieldErosion leads to the loss of fertile land, decreasing crop yields and food security.
    Disruption of Aquatic EcosystemsSediments from eroded soil can pollute water bodies, leading to the destruction of aquatic habitats and biodiversity.
    Increased DesertificationContinuous erosion can turn fertile lands into deserts, leading to the expansion of arid regions.
    Climate Change ContributionSoil erosion can release stored carbon from the soil into the atmosphere, contributing to greenhouse gas emissions.
    Loss of BiodiversityErosion leads to habitat destruction, affecting both flora and fauna dependent on stable soil for survival.
    Water Cycle DisruptionSoil erosion affects the water retention capacity of land, leading to altered water cycles and increased runoff.
    Economic ImpactIt causes economic losses in agriculture, forestry, and infrastructure due to decreased land productivity and increased maintenance costs.

    By diminishing the quality of soil and degrading ecosystems, soil erosion poses a significant threat to the sustainability of the biosphere, impacting all living organisms that depend on the land for survival.

    Correct Answer: All three

    Explanation:

    1. It can be used directly as a fuel for internal combustion:
      Correct. Green hydrogen can be used as a fuel in internal combustion engines (ICEs) with modifications. Hydrogen combusts cleanly, emitting only water vapor as a byproduct, making it a potential alternative to traditional fuels.
    2. It can be blended with natural gas and used as fuel for heat or power generation:
      Correct. Green hydrogen can be blended with natural gas and used in existing gas pipelines to generate heat or power. This helps reduce carbon emissions and makes use of existing infrastructure.
    3. It can be used in the hydrogen fuel cell to run vehicles:
      Correct. Hydrogen fuel cells convert green hydrogen into electricity, which can power vehicles. This is already being implemented in hydrogen-powered vehicles, which emit only water vapor.

    Thus, all three statements are correct.

    Correct Answer: All three

    Explanation:

    1. Gold mining activity is a source of mercury pollution in the world:
      Correct. Artisanal and small-scale gold mining (ASGM) is one of the largest global sources of mercury emissions. Mercury is used in the extraction process to amalgamate gold, releasing significant amounts of mercury into the environment.
    2. Coal-based thermal power plants cause mercury pollution:
      Correct. Coal contains trace amounts of mercury. When coal is burned in thermal power plants, mercury is released into the atmosphere as a pollutant.
    3. There is no known safe level of exposure to mercury:
      Correct. Mercury is highly toxic, and even low levels of exposure can lead to serious health effects. The World Health Organization (WHO) states that there is no safe threshold for mercury exposure, particularly for vulnerable groups such as pregnant women and children.

    Hence, all three statements are correct.

    The sky appears blue due to a phenomenon known as Rayleigh scattering. This occurs when sunlight passes through Earth’s atmosphere, which contains gases and tiny particles. Sunlight, or white light, is made up of different colors, each with a different wavelength. Blue light has a shorter wavelength and is scattered more easily than colors with longer wavelengths, like red or yellow.

    As sunlight interacts with the molecules in the atmosphere, the shorter wavelengths of blue light are scattered in all directions, making the sky look blue to our eyes. This scattering effect is stronger for blue light because of its shorter wavelength compared to other colors in the visible spectrum.

    At sunrise and sunset, when the sun is lower in the sky, its light passes through more of Earth’s atmosphere, scattering even more of the shorter wavelengths and allowing the longer wavelengths, like red and orange, to dominate the sky’s color.
