The human cost of a deadly weed killer: banning of paraqua in Telangana

In India, the use of carbofuran, methyl parathion, phorate and triazophos is viewed with apprehension because they are all pesticides used in agriculture. These pesticides are considered hazardous due to their potential negative impacts on human health and the environment.

Statement 1 is Correct: The National Institute for Research and Application of Natural Resources to Transform, Adapt and Build Resilience (NIRANTAR) is a collaborative platform under the Ministry of Environment, Forest and Climate Change (MoEFCC). Ecosystem Survey & Analysis is one of its four thematic verticals, and its lead institute is the Botanical Survey of India (BSI), Kolkata. Statement 2 is Incorrect: The Research and Management of Ecosystem Service vertical is led by the Indian Council of Forestry Research and Education (ICFRE), Dehradun, not the Central Zoo Authority (CZA). The CZA is merely a participating institute under this vertical. Statement 3 is Correct: The Capacity Development Support vertical focuses on research, education, and capacity building. The lead institute for this vertical is the Indian Institute of Forest Management (IIFM), Bhopal. Therefore, option B is the correct answer.

At COP28, India chose not to sign the “Declaration on Climate and Health,” and this decision can be understood by analyzing the nature of the declaration and India’s concerns. ✅ Statement I: Correct. India did not sign the COP28 Declaration on Climate and Health, unlike over 120 other countries. ❌ Statement II: Incorrect. The declaration is not legally binding; it is a voluntary political commitment. Signing it does not legally mandate countries to decarbonize their health sectors immediately. ✅Statement III: Correct. India’s concern is that rapid decarbonization of its health sector could compromise the resilience and accessibility of healthcare services, given current developmental challenges and resource constraints. Therefore, only Statement III correctly explains Statement I, while Statement II is factually wrong about the binding nature of the declaration.

* Statement 1 is incorrect: The Mundra Thermal Power Plant employs a closed-cycle induced draft circulating cooling water system that utilises seawater. Seawater is drawn from the Gulf of Kutch through robust glass reinforced pipes of significant diameter. In addition, purified seawater from a reverse osmosis plant is utilised by various supplementary systems. * Statement 2 is incorrect:  According to recent research by WRI (World Resources Institute), 40 percent of India's thermal power plants are situated in regions experiencing significant water stress. This poses a challenge as these plants rely on water for cooling purposes. The scarcity of water is already causing disruptions in electricity generation in these areas, with 14 out of India's 20 largest thermal utilities having experienced at least one shutdown between 2013 and 2016 due to water shortages. * Statement 3 is incorrect:  India has a total of 269 Thermal Power Plants, with 138 of them being owned by the public sector and the remaining 131 owned by the private sector.

Central Ground Water Authority (CGWA) has been constituted under Section 3 (3) of the Environment (Protection) Act, 1986 to regulate and control development and management of groundwater resources in the country. Central Water Commission (CWC) - Established in 1945, the CWC is a technical organization under the Ministry of Jal Shakti. It focuses on water resource planning, development, and management in India, but its legal basis comes from other central government acts. Central Ground Water Board (CGWB) - While it works in close collaboration with the CGWA, the CGWB is a subordinate organization under the Ministry of Jal Shakti, established in 1970. It functions as the technical arm of the CGWA, providing hydrogeological data and technical expertise. National Water Development Agency (NWDA) - This autonomous agency, established in 1982 under the Ministry of Jal Shakti, operates under the Societies Registration Act, 1860. It focuses on resolving interstate water resource disputes, conducting feasibility studies for water resource development projects, and planning water transfer and linking projects.

Statement 1 is incorrect. The production of algae-based biofuels is not limited to seas only. It can be done on land, saline water, or wastewater. Statement 2 is correct. Setting up and engineering the algae-based biofuel production does require a high level of expertise/technology, which might be a limitation for developing countries. Statement 3 is also correct. Economically viable production of algae-based biofuels does necessitate the setting up of large-scale facilities, which may raise ecological and social concerns.

The Climate Action Tracker (CAT) is an independent scientific analysis that tracks government climate action and measures it against the globally agreed Paris Agreement aim of holding warming well below 2C, and pursuing efforts to limit warming to 1.5C. A collaboration of two organisations, Climate Analytics and NewClimate Institute, the CAT has been providing this independent analysis to policymakers since 2009. CAT quantifies and evaluates climate change mitigation targets, policies, and actions. It also aggregates country action to the global level, determining likely temperature increases during the 21st century using the MAGICC climate model. CAT further develops sectoral analysis to illustrate the required pathways for meeting the global temperature goals.

Statement 1 is incorrect: Nanoparticles can exist in nature (natural nanoparticles). Volcanic eruptions, forest fires, and natural weathering processes can all create nanoparticles. Statement 2 is correct: Some cosmetics incorporate nanoparticles of ingredients like zinc oxide or titanium dioxide for sun protection or other purposes. Statement 3 is also correct: The safety of nanoparticles in consumer products is a complex issue and a growing area of research. Some nanoparticles might pose potential health or environmental risks depending on their specific properties and how they interact with the body or the environment.

Statement 1 is Correct: The OEKO-TEX certification ensures that textiles are rigorously tested and proven free from harmful substances, heavy metals, and toxic chemicals. This certification acts as a major endorsement, directly enhancing the global marketability of Eri Silk and allowing Indian exporters to confidently compete in high-end international markets that prioritize sustainable, chemical-free, and ethically produced textiles. Statement 2 is Correct: The certification confirms that a textile meets strict international safety, environmental, and human health standards. This is highly valued by buyers in premium, eco-conscious global markets, particularly in Europe and North America. Combined with its Geographical Indication (GI) status and reputation as a cruelty-free "peace silk," the certification cements Eri Silk's position as a premium eco-friendly fabric, enabling its entry into these premium markets. Therefore, both statements are correct, making the correct option C.

The term 'Social Cost of Carbon' is a measure of the economic damages, in dollars, that would result from emitting one additional ton of carbon dioxide into the atmosphere. It is used to value the climate impacts of rulemakings and helps policymakers understand the economic impacts of decisions that would increase or decrease emissions. Therefore, it is best described as the long-term damage done by a tonne of carbon dioxide emissions in a given year.
