Question

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

Short answer

The correct answer is (d) all of these.

Step-by-step solution

Analyze Each Option

We start by evaluating each given option to see if it helps in controlling pollution. Option (a) involves developing bio remedies, which are biological methods to clean up polluted areas. This can include using microorganisms to break down pollutants. Option (b) suggests planting trees, which help in absorbing carbon dioxide and improving air quality. Option (c) focuses on controlling population growth, which can lead to less environmental stress and reduced pollution.

Consider Comprehensive Solutions

Pollution often requires a multifaceted approach to address its different sources and effects. Although each option can contribute to pollution control independently, combining these strategies can offer a more comprehensive solution. Bio remedies target contaminated environments, planting trees improve air quality, and managing population growth reduces resource strain.

Evaluate 'All of These' Option

Consider option (d), which encompasses all the previous options. This approach is broader and ensures that various facets of pollution control are addressed, increasing the efficiency and effectiveness of the efforts.

Choose the Best Option

Conclude that all strategies (developing bio remedies, planting trees, controlling population growth) collectively lead to better pollution management. Thus, the most inclusive and effective answer is option (d) 'all of these'.

Key concepts

Bio Remedies

Bio remedies refer to the use of living organisms, like microorganisms, plants, or enzymes, to help clean up polluted environments. These methods are an excellent choice for pollution control because they offer a natural way to address contamination without introducing further chemicals into the environment.
Bio remedies encompass techniques such as bioremediation and phytoremediation.

• Bioremediation uses microorganisms to break down hazardous substances into less harmful products. These microorganisms consume pollutants as a source of energy, effectively cleaning up soil and water.
• Phytoremediation involves using plants to absorb, filter, and detoxify pollutants from soil and water. This method is particularly effective in treating heavy metal contamination.

Bio remedies are sustainable, preserving the natural habitat, and are generally cost-effective. They are especially valuable in areas where conventional cleaning methods might be too harsh or expensive.

Afforestation

Afforestation is the process of planting trees in barren or deforested land. This method plays a critical role in pollution control by improving air quality and promoting biodiversity.
Trees absorb carbon dioxide, a major greenhouse gas, and release oxygen, which is essential for human and animal life.

• They act as natural air filters by trapping dust, pollen, and other pollutants from the air.
• Tree roots stabilize the soil, prevent erosion, and maintain the water cycle, reducing the risk of natural disasters.

Afforestation also creates wildlife habitats, supports ecosystem stability, and contributes to the cooling effect by providing shade and releasing water vapor through a process called transpiration. This makes afforestation an effective way to combat both pollution and climate change.

Population Management

Population management involves implementing strategies to control or reduce the rate of population growth. As populations grow, so does the demand for resources such as water, food, and energy, leading to increased pollution.
Managing population growth can significantly decrease the environmental stress and help lower pollution levels.

• Efforts can include family planning education, which helps individuals understand and access reproductive health resources.
• Encouraging policies that promote sustainable resource use and waste management supports long-term environmental health.

By focusing on population management, societies can work towards creating a balance between human needs and environmental sustainability. This approach not only aids in pollution control but also supports economic and social development by ensuring resources are used efficiently and equitably.
