Given below are two statements:
Statement I: Deforestation contributes to global warming because it increases the amount of carbon dioxide in the atmosphere.
Statement II: Methane gas released in animal waste is one of the factors that may be contributing to global warming.
In the light of the above statements, choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Both Statement I and Statement II are true.
Statement I: Deforestation contributes to global warming because it increases the amount of carbon dioxide in the atmosphere. — True. Fewer trees leave more carbon dioxide in the air.
Statement II: Methane gas released in animal waste is one of the factors that may be contributing to global warming. — True. Methane from animal waste is also a greenhouse gas.
NCERT (2026-27): “Box 7.1: Global Warming … Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide, methane, nitrous oxide, ozone); deforestation, which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production, which contributes to deforestation, methane production, and use of fossil fuels. A UN Conference on Climate Change, held in Kyoto, Japan, in 1997, resulted in an international agreement to fight global warming which called for reductions in emissions of greenhouse gases by industrialised nations.” |
