A company wants to reduce long-term environmental pollution from its packaging materials. Which material should it choose to avoid lasting environmental damage?

Appeared in: RRB Nsg. Superintendent-2026 (Shift -3rd)

Explanation

The question asks for a material that avoids long-term environmental damage.
Materials that can be decomposed by natural processes are called biodegradable.
These materials are broken down by microorganisms (like bacteria and fungi) and are integrated back into the ecosystem.
This process prevents the accumulation of waste in landfills and oceans, thus avoiding lasting pollution.
Choosing biodegradable packaging is a key strategy for environmental sustainability.

Option A: An inert material, like most plastics, does not decompose. While it may not chemically react, its physical presence persists for hundreds of years, contributing to landfill volume and breaking down into harmful microplastics.
Option C: This option describes the very problem the company is trying to avoid. A material that remains unchanged for decades is a persistent pollutant that causes long-term environmental harm.
Option D: Choosing a material that is actively harmful to the ecosystem is the opposite of the stated goal. Such materials would cause immediate and direct damage to flora and fauna.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Environmental pollution and sustainable materials as background academic context rather than a clinical decision trigger.
Environmental health is a crucial component of community health nursing. Pollution from non-degradable waste can contaminate water and soil, leading to public health crises.
Persistent pollutants like microplastics and heavy metals can enter the food chain through a process called bioaccumulation, posing risks to human health, including endocrine disruption and other chronic diseases.
Nurses can play a role in advocating for and educating communities on sustainable practices to reduce exposure to environmental hazards and promote long-term health.

How to Approach the Question

First, identify the core requirement of the question: to 'reduce long-term environmental pollution' and 'avoid lasting environmental damage'.
Analyze the meaning of 'long-term' and 'lasting'. This implies the material should not persist in the environment.
Evaluate each option against this requirement.
Option A (inert) and C (unchanged for decades) describe materials that persist. Eliminate them.
Option D (harmful) is directly contrary to the goal. Eliminate it.
Option B (decomposed by natural processes) describes a material that will not persist, directly addressing the problem of long-term pollution. This is the correct choice.
