Problem 29 - A Complete Resource Book in Chemistry for JEE Main

Question

Control of pollution is possible by (a) developing bio remedies (b) planting trees (c) controlling the population growth (d) all of these

Step-by-Step Solution

Answer

The answer is (d) all of these.

Step 1: Understand the question

The exercise asks which measures can contribute to controlling pollution, providing different options. Analyze what each option suggests.

Step 2: Analyze option (a)

Option (a) suggests developing bio remedies as a way to control pollution. Bio remedies refer to the use of biological methods, such as microorganisms or plants, to neutralize or remove pollutants from the environment.

Step 3: Analyze option (b)

Option (b) proposes planting trees to control pollution. Trees absorb carbon dioxide and other pollutants, helping to clean the air and improve environmental health.

Step 4: Analyze option (c)

Option (c) mentions controlling population growth as a way to manage pollution. More people can lead to increased resource use and waste production, thereby contributing to pollution.

Step 5: Consider option (d)

Option (d) suggests that all the listed measures (a, b, and c) are viable solutions for controlling pollution. This implies that each method contributes to the overall reduction of pollution.

Step 6: Conclusion

Since all the given options (developing bio remedies, planting trees, and controlling population growth) can aid in reducing pollution, the most comprehensive choice is (d), which includes all of these measures.

Key Concepts

Bioremediation

Bioremediation is a fascinating and effective method for dealing with environmental pollution. It involves using living organisms, often microorganisms like bacteria and fungi, to clean up contaminated environments. These organisms break down harmful pollutants into less toxic substances. This process can occur naturally, known as natural attenuation, or be enhanced by human intervention, known as biostimulation.
Bioremediation offers several advantages:

• Environmentally friendly, as it uses natural processes.
• Cost-effective compared to many conventional cleanup methods.
• Reduces waste by converting pollutants into less harmful substances.

An exciting application of bioremediation is in oil spill responses, where specific bacteria decompose the hydrocarbons in oil, significantly reducing the environmental impact. Another application is in treating wastewater, transforming toxic chemicals into harmless ones. Bioremediation is an excellent example of how we can work with nature to solve pollution problems.

Reforestation

Reforestation is a powerful tool against pollution. It involves the replanting of trees in areas where forests have been depleted. Trees are vital for our environment, as they absorb carbon dioxide, provide oxygen, and filter out harmful particulates, improving air quality. By implementing reforestation, we help restore ecosystems and enhance biodiversity.
There are several key benefits of reforestation:

• Mitigates air pollution by trapping dust, ash, pollen, and smoke.
• Helps reduce greenhouse gases, combating climate change.
• Offers habitat for wildlife, maintaining ecological balance.

A unique method of reforestation is using drones to quickly and efficiently plant large numbers of trees in inaccessible areas. This innovative technique has a significant impact on restoring depleting forests. By focusing on reforestation, we invest not only in reducing pollution but also in the health of our planet for future generations.

Population Control

Population control plays a critical role in managing and reducing pollution. As the global population increases, so does the demand for resources such as water, energy, and land, leading to elevated pollution levels. More people result in more waste production, increased carbon emissions, and greater environmental degradation.
Population control involves implementing strategies to stabilize or reduce the population size to sustainable levels. Important strategies include:

• Promoting family planning and education about reproductive health.
• Increasing women's access to education and employment opportunities.
• Encouraging policies that balance population growth with resource availability.

By controlling population growth, we can better manage resource allocation and reduce the strain on the environment. This leads to more sustainable development, less pollution, and a healthier planet for all. Population control represents a foundational approach to addressing environmental concerns and ensuring long-term ecological balance.
