Question : Statement 1: E-waste recycling is an essential aspect of sustainable waste management.
Statement 2: Improper disposal of electronic waste can lead to environmental pollution and the release of hazardous substances into the ecosystem.
Option 1: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Option 2: Both statement 1 and statement 2 are true, but statement 2 is not the correct explanation of statement 1 .
Option 3: Statement 1 is true, but statement 2 is false.
Option 4: Statement 1 is false, but statement 2 is true.
Correct Answer: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Solution : The correct option is (A) Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Statement 1 is true: E-waste recycling is indeed an essential aspect of sustainable waste management. Electronic waste, or e-waste, consists of discarded electronic devices such as computers, smartphones, and appliances. Recycling e-waste helps recover valuable materials, such as metals and plastics, which can be reused in the manufacturing of new products. By recycling e-waste, we reduce the need for extracting raw materials, conserve resources, and minimize the environmental impact associated with the production of new electronic devices.
Statement 2 is the correct explanation of statement 1. Improper disposal of electronic waste can lead to environmental pollution and the release of hazardous substances into the ecosystem. When e-waste is not recycled properly, it often ends up in landfills or is incinerated, leading to environmental problems. E-waste contains toxic substances such as lead, mercury, cadmium, and brominated flame retardants, which can leach into the soil and water, posing risks to human health and the environment. Therefore, proper recycling and disposal of e-waste are necessary to prevent pollution and the release of hazardous substances.
Both statements are true, and statement 2 provides the correct explanation for statement 1 .
Question : Statement 1: Waste segregation at source is an effective waste management practice that involves separating different types of waste for proper disposal or recycling.
Statement 2: Waste segregation helps reduce the burden on landfill sites, promotes recycling, and minimizes environmental pollution.
Question : Statement 1: The conservation of biodiversity is essential for sustainable development as it provides various ecosystem services, including pollination, nutrient cycling, and climate regulation.
Statement 2: Biodiversity loss can disrupt ecosystem functioning, reduce ecosystem resilience, and have negative impacts on human well-being.
Question : Statement 1: The concept of circular economy promotes reducing, reusing, and recycling materials to minimize waste generation and resource consumption.
Statement 2: Circular economy principles aim to create a closed-loop system where resources are kept in use for as long as possible.
Question : Statement 1: The sustainable management of forests is crucial for maintaining biodiversity, mitigating climate change, and providing livelihoods for local communities.
Statement 2: Deforestation and forest degradation result in the loss of habitat, increased greenhouse gas emissions, and reduced ecosystem services.
Question : Assertion: E-waste management is crucial for sustainable development as electronic waste contains hazardous substances that can pollute the environment.
Reason: Proper e-waste management involves recycling and proper disposal of electronic devices to prevent environmental contamination.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.
Option 4: Assertion is incorrect, but the reason is correct.
