The industrial activity held least responsible for global warming is :
Show Hint
Understand the industrial processes that contribute to greenhouse gas emissions and their relative impact on global warming.
- steel manufacturing
- manufacturing of cement
- Industrial production of urea
- Electricity generation in thermal power plants
The Correct Option is C
Solution and Explanation
Manufacturing of cement, steel manufacturing, and electricity generation in thermal power plants are major contributors to greenhouse gas emissions, primarily CO2, which is a significant driver of global warming.
Cement production releases CO2 through the calcination of limestone.
Steel manufacturing uses coal, a carbon-intensive fuel, releasing CO2.
Thermal power plants also burn fossil fuels to generate electricity, leading to substantial CO2 emissions.
While urea production does have an environmental footprint, its contribution to global warming is much less than the other three activities listed. The primary greenhouse gas emissions associated with urea production are nitrous oxide (N2O) from fertilizer application and CO2 from energy use in the production process. However, these emissions are considerably lower compared to those from cement, steel, and electricity generation.

Concepts Used:
Environmental Pollution
When there is an unpleasant change in the surrounding that has harmful effects on plants and animals, it leads to environmental pollution. Pollution is the root cause of a substance - “pollutant”. We can have pollutants in solid, liquid, or gaseous forms. A substance becomes a pollutant when its concentration is greater than the natural abundance and this increase in concentration is either because of human activities or natural phenomena.
Effects of Environmental Pollution:
Some pollutants are scraped into the soil by human beings. This leads to air, water, and soil pollution. If the soil is polluted, the helpful or functional microorganisms in it will die and the fertility of the soil will vanish. The production of crops will diminish. If the soil is not fertile; it will have a harmful consequence on human society.
