Question

Which one is not a correct statement regarding the minimization of pollution? (a) manures and biofertilizers should be used in place of chemical fertilizers. (b) all nuclear tests must be stopped. (c) green belts in cities should be developed. (d) domestic garbage must be burnt.

Short answer

Option (d) is not correct.

Step-by-step solution

Understand the Statements

Each statement suggests a measure for pollution minimization. Evaluate each one to identify if it aligns with pollution reduction principles.

Analyze Option (a)

Consider the impact of using manures and biofertilizers instead of chemical fertilizers. Manures and biofertilizers are natural and environmentally friendly, reducing chemical runoff and soil degradation.

Analyze Option (b)

Evaluate the impact of stopping all nuclear tests. Stopping nuclear tests would prevent radioactive pollution and reduce the risk of environmental contamination.

Analyze Option (c)

Consider the benefits of developing green belts in cities. Green belts improve air quality, reduce urban heat, and provide environmental benefits, thus contributing to pollution minimization.

Analyze Option (d)

Assess the impact of burning domestic garbage. Burning garbage releases harmful pollutants and toxic chemicals into the atmosphere, which goes against pollution reduction efforts.

Identify the Incorrect Statement

Compare the analyzed options and identify the one that does not contribute to pollution reduction. Option (d) is identified as incorrect, as burning domestic garbage increases pollution.

Key concepts

manures and biofertilizers

Manures and biofertilizers are essential for sustainable agriculture. They serve as natural alternatives to chemical fertilizers.
They enrich the soil with organic matter and essential nutrients without harming the environment.
Biofertilizers commonly include nitrogen-fixing bacteria, mycorrhizal fungi, and other beneficial microbes.
Using these natural fertilizers can:

• Improve soil fertility
• Enhance soil structure and water retention
• Reduce the dependency on chemical-based fertilizers, which can cause soil and water pollution

By using manures and biofertilizers, farmers contribute towards a healthier ecosystem and reduce the risks associated with chemical fertilizers, such as runoff into water bodies and soil degradation.

nuclear tests

Nuclear tests pose significant environmental and health risks. Conducting these tests releases radioactive materials, which can have long-lasting harmful effects.
Some critical impacts of nuclear tests include:

• Radioactive pollution contaminating air, water, and soil
• Health hazards such as cancer and genetic mutations for living organisms exposed to radiation
• Displacement of communities living near testing sites

By stopping all nuclear tests, we can prevent further radioactive contamination and safeguard both human health and the environment.
International agreements and treaties have been established to promote the cessation of nuclear tests and urge nations to seek peaceful alternatives.

green belts

Green belts are key to urban planning and environmental sustainability. These are designated areas of vegetation around cities and towns.
The development of green belts offers several benefits:

• Improving air quality by absorbing pollutants and producing oxygen
• Reducing urban heat islands effect by providing shade and cooler surfaces
• Enhancing the aesthetic value of urban areas
• Providing recreational spaces for citizens

Establishing green belts helps counteract the adverse effects of urbanization and promotes a healthier living environment.
They serve as lungs for our cities, contributing to pollution minimization and the well-being of urban populations.

domestic garbage

Proper disposal and management of domestic garbage are crucial in minimizing pollution. Burning domestic garbage is harmful because it releases toxic pollutants into the air.
These pollutants include:

• Carbon monoxide (CO)
• Dioxins and furans
• Particulate matter (PM)
• Heavy metals such as mercury and lead

Instead of burning, alternative methods for garbage disposal should be implemented, such as:

• Recycling and composting biodegradable waste
• Proper segregation of waste at the household level
• Promoting the use of reusable products to reduce overall waste

Through these measures, we can prevent the release of harmful pollutants into the atmosphere and protect both environmental and public health.
