Opportunity costs of environmental degradation refer to the massive expenditures needed to repair ecological damage and manage public health crises. Non-conventional energy sources help mitigate future damage, but the systemic opportunity costs of historical and ongoing environmental degradation remain massive and are far from negligible. Therefore, the Assertion is false, while the Reason accurately describes these heavy financial burdens.

Herman Daly formulated clear, foundational rules for maintaining ecological sustainability. For renewable resources, the sustainable rule dictates that consumption must not outpace the environment's natural capacity to restock itself. If the rate of extraction exceeds the rate of regeneration, the resource base shrinks, creating a severe sustainability crisis.

Traditional biomass cookstoves release high amounts of toxic particulate smoke into rural homes and waste large amounts of thermal energy. Liquid Petroleum Gas (LPG) burns highly efficiently and cleanly inside homes. This upgrade drastically reduces indoor air pollution and protects public health while minimizing energy waste.

Financial subsidies for gobar gas help lower upfront costs to encourage cleaner rural energy adoption (1 > a). Raw cattle dung provides the organic material needed to feed a biogas digester (2 > b). Processed slurry from the digester serves as an excellent organic soil conditioner (3 > c). Relying on widespread biomass burning leads to deforestation and a shrinking green cover (4 > d).

Urban centers face severe air quality challenges due to dense traffic and older diesel engines. Petrol and diesel vehicles release high volumes of particulate matter and nitrogen oxides at street level. Switching fleets to Compressed Natural Gas (CNG) directly targets and lowers these harmful ground-level emissions.

Urban environmental issues follow a clear path from cause to public impact, policy action, and results. The process begins with a massive increase in vehicles on city roads (4). This traffic boom causes ground-level vehicle emissions to peak at hazardous levels (2). In response, city planners implement policies like CNG mandates and odd/even traffic rules (3). These interventions lead to a noticeable lowering of urban air pollution (1).

Herman Daly stated that sustainable development requires clean technology that improves input efficiency and reduces pollution. Wind power captures a naturally occurring, infinite resource (moving air currents). This generation method produces electricity without wasting fuel or releasing pollution.

Statement I is incorrect because building wind farms requires a high initial capital investment for turbines, land, and grid connections. Statement II is incorrect because wind turbines have minimal ongoing fuel or operational costs, allowing them to recover their initial investment over time. Statement III is correct because wind generation produces clean electricity without releasing harmful emissions or causing adverse environmental impacts.

Thermal power plants burn coal, which releases large amounts of greenhouse gases like carbon dioxide ($CO_2$) and produces solid fly ash waste. Solar photovoltaic cells generate electricity directly from sunlight without burning fuel. This allows solar power to replace coal generation and eliminate carbon emissions and fly ash waste.

Connecting isolated villages to a central power grid requires building expensive transmission lines over difficult terrain. Solar energy can be set up directly in these communities using standalone solar panels and batteries. This provides a cost-effective, off-grid power solution for remote areas.

Large hydroelectric dams flood valleys, submerge forests, and displace local communities, radically altering land use. Mini-hydel plants are small, run-of-the-river installations that do not require building large dams or reservoirs. They capture energy from the natural flow of small streams, leaving the surrounding land use unchanged.

Moving electricity over long distances through high-voltage wires causes considerable energy waste through transmission losses. Generating power locally with mini-hydel plants allows electricity to be used right where it is made. This creates a highly input-efficient technological system that aligns with sustainable development goals.

Modern industrial practices often view nature as a resource base to be managed and exploited for maximum economic output. Traditional Indian culture views human society as an interconnected part of the natural world. This perspective integrates humans as components of the environment, rather than its controllers.

Ayurveda and Unani offer natural therapies that treat health conditions without the side effects of some western medicines (1 > b). Herbal cosmetics rely on plant extracts, which significantly reduces the need for synthetic chemical processing (2 > a). Local folk traditions represent an oral indigenous knowledge base in regular use across rural areas (3 > c). India's 15,000 plant species reflect the country's rich medicinal biodiversity (4 > d).

The Green Revolution relied heavily on synthetic chemical fertilizers and pesticides to rapidly boost crop yields. Neglecting organic practices like biocomposting led to a steady decline in natural soil health and organic matter. Over-applying these chemicals eventually caused widespread groundwater contamination and degraded productive farmland.

Biocomposting through vermiculture follows a step-by-step biological and administrative sequence. First, organic waste is collected and fed to earthworms instead of being thrown away (2). Next, earthworms rapidly break down this organic matter into rich compost (3). Farmers then apply this nutrient-rich compost to their fields to improve soil health (4). By recycling this organic waste on farms, civic authorities see a reduced burden on city landfills (1).

Planting large fields with a single crop makes it easy for pest populations to multiply rapidly. Mixed cropping and crop rotation disrupt these pests by changing the plants available in the field over time. This practice breaks insect breeding cycles naturally, reducing the need for chemical pesticides.

Chemical pesticides can inadvertently kill beneficial wildlife and leave toxic residues on food crops. Biological pest control uses natural predators to keep pest populations in check. Supporting animals like snakes, owls, and peacocks near fields creates a natural defense system against rodents and insects.

This is a text-retrieval question based on the provided Brundtland Commission passage. The text outlines our ethical responsibility to future generations. It states we must leave behind a stock of quality of life assets no less than what we inherited.

This question tests your comprehension of the provided text on sustainable resource management. To protect long-term public welfare, we must hand over the planet in good condition. This requires pursuing development that protects and preserves our natural environment.
