Environmental catastrophe will be a tragedy authored by everyone

Statement 1 is incorrect: The Environment Protection Act (EPA), 1986 recognizes the importance of public participation in environmental decision-making. However, it does not explicitly define the procedure for public participation in environmental governance, such as public hearings or consultations. These provisions were later formalized through subsequent rules and notifications, such as the Environmental Impact Assessment (EIA) Notification, 2006, which mandates public hearings for certain projects. Statement 2 is correct: The EPA, of 1986 empowers the Central Government to Lay down environmental quality standards for air, water, and soil, Regulate emissions and discharges of pollutants from industries and other sources, Restrict hazardous substances and their handling, Take emergency measures to prevent environmental disasters.

1. Copper slag is a by-product generated during the extraction and refining of copper. It can be used as a partial replacement for sand in concrete production, thus reducing the demand for natural resources. This reduces the environmental impact associated with sand mining. 2. Cold mix asphalt technology involves producing asphalt mixtures at lower temperatures compared to traditional hot mix asphalt. This results in reduced energy consumption during production and lower emissions of greenhouse gases. Cold mix asphalt also allows for the use of recycled materials, further enhancing its environmental sustainability. 3. Geotextiles are synthetic materials used in road construction for various purposes such as soil stabilisation, drainage, and erosion control. They can help in reducing the need for excessive excavation and use of natural resources like stone and gravel, thereby minimizing environmental impact. 4. Hot mix asphalt technology involves producing asphalt mixtures at high temperatures. While it provides excellent performance properties for roads, it typically requires higher energy consumption during production compared to cold mix asphalt technology. 5. Portland cement is a key ingredient in concrete production. While it is widely used in construction, its production process is energy-intensive and emits significant amounts of carbon dioxide, contributing to greenhouse gas emissions. Therefore, the correct answer is A. 1, 2, and 3 only.

The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion . Bretton woods conference is related to establishment of World Bank and IMF in 1945.
Kyoyo protocol is related to Climate Change conference.
Nagoya protocol is related to Convention on BIological Diversity.

Statement 1 is correct. National Ganga River Basin Authority (NGRBA) is the financing, planning, implementing, monitoring, and coordinating authority for the Ganges River, functioning under the Jal Shakti Ministry. Statement 2 is correct. The mission of the organisation is to safeguard the drainage basin which feeds water into the Ganges by protecting it from pollution or overuse. In July 2014, the NGRBA has been transferred from the Ministry of Environment and Forests to the Ministry of Jal Shakti. Statement 3 is incorrect. The Prime Minister is the chair of the Authority.
Other members include the cabinet ministers of ministries that include the Ganges among their direct concerns and the chief ministers of states through which the Ganges River flows.

* The R2 Code of Practices is a tool available for promoting the adoption of environmentally responsible practices in the electronics recycling industry. * R2 stands for Responsible Recycling.
The Code of Practices outlines a set of standards that electronics recyclers should follow to ensure responsible handling of electronic waste.

Extended Producer Responsibility (EPR) in E-waste Management Rules, 2011 Makes producers of electrical and electronic equipment (EEE) responsible for the collection and channelization of e-waste after its end-of-life. This promotes responsible production and encourages proper e-waste disposal. EPR in Plastic Waste Management Rules, 2016 Extends the EPR principle to plastic waste. Producers, importers, and brand owners are accountable for managing plastic packaging waste after consumption.

* Solid Waste Management Rules, 2016 mandate the segregation of waste into three categories - biodegradables, dry recyclables (plastic, paper, metal, etc.), and domestic hazardous waste (diapers, napkins, etc.). * The SWM Rules, 2016 apply not just to urban areas but also to urban local bodies, notified areas, census towns, all industrial townships, special economic zones, State and Central government organisations, places of pilgrimage, religious and historical importance. * There is no restriction on moving waste from one district to another. Waste generators can transport waste as needed for disposal, treatment, or processing. * Waste processing facilities will have to be set up by all local bodies having a population of 1 million or more within two years. * For census towns with a population below 1 million or all local bodies having a population of 0.5 million or more, common, or stand-alone sanitary landfills will have to be set up in three years. * Also, common, or regional sanitary landfills to be set up by all local bodies and census towns with a population under 0.5 million will have to be completed in three years.

Triclosan (sometimes abbreviated as TCS) is an antibacterial and antifungal agent present in some consumer products, including
- toothpaste,
- soaps,
- detergents,
- toys,
- surgical cleaning treatments.

Statement 1 is correct. The WHO recommends that the 24-hour mean of PM2.5 should not exceed 15 ug/m³ and the annual mean should not exceed 5 ug/m³. These are the current most stringent guidelines set by WHO to protect public health. Statement 2 is incorrect. Ozone pollution typically peaks during sunny and stagnant weather conditions, not during inclement weather like rain or storms. Statement 3 is incorrect. While PM10 (≤ PM10) particles can enter the deep lungs and cause respiratory issues, it's the much finer PM2.5 (≤ PM2.5) particles and ultrafine particles that effectively penetrate the lung barrier (alveoli) to enter the bloodstream, affecting the heart, brain, and other organs. PM10 typically deposits in larger airways, whereas PM2.5's tiny size allows it to cross into the circulatory system, making it more dangerous.  Statement 4 is correct. Excessive ozone exposure can trigger asthma attacks and worsen respiratory problems. Ozone irritates the respiratory tract, making it harder to breathe.

Statement 1 is incorrect: As per the report National Compilation on Dynamic Groundwater Resources of India, 2017 of CGWA, out of the total 6881 assessment units (Blocks/Mandals/ Talukas) in the country, 1186 units in various States (17%) have been categorized as Over-Exploited, 313 units (5%) as Critical, and 972 units (14%) as Semi-Critical. Statement 2 is correct: The CGWA was established in 1997 under Section 3(3) of the Environment (Protection) Act, 1986 to regulate and manage groundwater resources. Statement 3 is correct: India has the largest area under groundwater irrigation in the world. This is due to the country's heavy reliance on agriculture, which is predominantly rain-fed. Therefore, the correct answer is B. 2 and 3 only.
