Answer:

The poem is a conversation between the poet and the rain. When the poet asks the identity of the drizzle, she replies that she is the poem of the Earth. The rain expresses that it gives happiness to mother Earth.

Though it changes its form or shape, its originality remains unchanged. It shows that nature is not fully understood. Some parts of it always remain mysterious.

The raindrops pour down from above to wash away atomies and dust layers. It quenches the thirst of the dry Earth and heals everything that is becoming lifeless. In other words, the showers make the Earth pure and beautiful.

Finally, the poet observes that the life of rain is similar to that of a song. A song also has the power to calm, heal, transform and thrill. In the same way, repeated evaporation and condensation purifies the rain. It beautifies the whole earth as a rhythm does to a poem or a music.

Answer:

 

Khairahani-4, Chitwan

June 7, 2023

To
The Mayor,

Khairahani Municipality, Chitwan

Dear Sir,

 

I'm writing to draw your attention to a critical problem that's been affecting our locality, specifically the unmanaged garbage issue. I bring up this issue since it not only endangers the environment but also has serious negative effects on public health.

 

The amount of junk that has accumulated in our neighborhood over the last few months has gotten seriously out of hand. Ineffective waste management practices have resulted in overflowing trash cans, street litter, and an ugly environment in general. The unmanaged garbage not only emits foul odors but also attracts pests such as rats, flies, and mosquitoes, which are known carriers of diseases.

 

Uncontrolled waste poses a wide range of risks to public health. The airborne poisonous compounds and hazardous gases released by the decomposing garbage might result in respiratory conditions, allergic reactions, and other health difficulties. The risk of vector-borne illnesses including dengue, malaria, and cholera is increased by the presence of pests attracted to the rubbish. Additionally, the uncontrolled rubbish creates unsanitary conditions that serve as a breeding ground for germs and other infections.

 

Considering the gravity of the situation, I urge the concerned authority to take immediate action to address this problem. Here are some measures that could help alleviate the unmanaged garbage issue and improve public health:

 

Increase the frequency of garbage collection: Increasing the frequency of garbage collection is necessary to avoid rubbish accumulation and the problems that result from it. To satisfy the needs of our community, the current collection schedule must be amended because it is insufficient.

 

Implement segregation at source: Encourage and educate residents about the importance of waste segregation at the source. Provide clear guidelines and distribute color-coded bins for different types of waste (e.g., organic, recyclable, and non-recyclable) to facilitate proper disposal.

 

Create recycling facilities: Open recycling facilities in your community to encourage the reuse and recycling of waste products. This will support a more sustainable environment by lowering the amount of waste that is dumped in landfills.

 

Promote awareness programs: To inform the public about the correct disposal of waste, the value of preserving cleanliness, and the potential health risks connected with uncontrolled rubbish, conduct regular awareness campaigns through community meetings, posters, and social media platforms.

 

Increase surveillance and penalties: In order to discourage littering and incorrect garbage disposal, increase surveillance and sanctions. Boost security in strategic locations and penalize those who disobey waste management laws with fines or other sanctions.

 

I firmly believe that by putting these measures into action, we can effectively address the unchecked rubbish issue in our neighborhood and produce a cleaner, healthier environment for everyone. The residents' health and welfare are at risk, thus I sincerely ask that you give this issue your immediate attention.

Thank you for your attention to this matter.

Yours sincerely,

Apekshya Pandit
