Questions and Solutions
Question 1
The question requires writing a formal letter to the Editor of a newspaper about the pollution issues in Kanpur and suggesting ways to mitigate them. Here is a sample letter:
A-43, Civil Lines,
Kanpur
14 January 2024
The Editor,
The Times of India,
New Delhi.
Subject: Urgent Attention Needed for Severe Pollution Problems in Kanpur
Sir,
I am writing to you through the esteemed columns of your newspaper to draw the attention of the concerned authorities, particularly the Chairman of the Municipal Corporation of Kanpur, towards the alarming levels of pollution plaguing our city. Kanpur, an industrial hub and home to millions, is suffering immensely from various forms of pollution, including air, water, and noise pollution.
Over the years, the proliferation of industrial units, especially in the chemical and tanning sectors, has significantly contributed to environmental degradation. Many of these industries do not adhere to the prescribed environmental and pollution control standards, leading to severe consequences for the city's inhabitants. The waste water disposal system is inadequate, resulting in waterlogging in many areas. Furthermore, the discharge of untreated industrial chemical waste directly into the river contaminates the water source, making it unfit for use. The air quality is critically poor, contributing to a rise in skin and lung diseases, and even cancer among residents. Adding to these woes, noise pollution from vehicular traffic, which often fails to meet emission and sound norms, creates a disturbing environment.
To address this critical situation, I urge the authorities to take immediate and decisive action. This should include the strict enforcement of relevant sections of environmental laws and the constitution to bring polluters to book. Additionally, implementing robust pollution control measures at industrial sites and improving waste management systems are crucial. Conducting widespread awareness campaigns to educate both industries and residents about the detrimental effects of pollution and promoting sustainable practices will be vital in bringing the problem under control.
Yours truly,
(Mr. Khurana)
