Question

The industrial activity held least responsible for global warming is :

• A. steel manufacturing
• B. manufacturing of cement
• C. Industrial production of urea
• D. Electricity generation in thermal power plants

Hint:

Understand the industrial processes that contribute to greenhouse gas emissions and their relative impact on global warming.

Answer 1

The Correct Option is C

To determine which industrial activity is least responsible for global warming, we need to analyze the emissions associated with each activity:

1. Steel Manufacturing: This process involves significant carbon dioxide (CO_2) emissions due to the combustion of fossil fuels and the chemical reduction of iron ore. The steel industry is a major contributor to greenhouse gases and thus, global warming.
2. Manufacturing of Cement: Cement production is known to release a substantial amount of CO_2 due to the calcination of limestone and the burning of fuel. It is one of the largest industrial contributors to greenhouse gas emissions.
3. Industrial Production of Urea: The production of urea primarily involves the conversion of ammonia and carbon dioxide into urea. While it involves the use of CO_2, this process emits relatively lower amounts of greenhouse gases compared to the other industries mentioned. Therefore, it is less responsible for global warming.
4. Electricity Generation in Thermal Power Plants: Typically uses coal, natural gas, or oil as fuel, resulting in high emissions of CO_2, making it a significant contributor to global warming.

Based on this analysis, the Industrial production of urea is the correct option, as it has the least impact on global warming compared to the others.
