About 15 per cent of global greenhouse gas emissions come from agricultural practices. This includes nitrous oxide from fertilizers; methane from livestock, rice production, and manure storage; and carbon dioxide (CO₂) from burning biomass, but this excludes CO₂ emissions from soil management practices, savannah burning and deforestation. Forestry, land use, and land-use change account for another 17 per cent of greenhouse gas emissions each year, three quarters of which come from tropical deforestation. The remainder is largely from draining sad burning tropical peatland. About the same amount of carbon is stored in the world’s peatlands as is stored in the Amazon rainforest.

Which among the following is the most logical aid rational inference that can be made from the above passage ?

The correct option is: It is imperative for us to modify our land use practices in order to mitigate climate change.

Step-by-step Explanation:

1. Analyze the Passage Information:
The passage states that agricultural practices contribute about 15% of global greenhouse gas emissions (including nitrous oxide from fertilizers, methane from livestock, rice production, and manure storage, and CO₂ from burning biomass).
Additionally, forestry, land use, and land-use change account for another 17% of greenhouse gas emissions each year, with three-quarters of this portion coming from tropical deforestation and the remainder largely from draining and burning tropical peatland.

2. Evaluate the Options:
• "Organic farming should immediately replace mechanised and chemical dependant agricultural practices...": This is an extreme policy recommendation. While the passage mentions fertilizers contributing to nitrous oxide emissions, it does not provide evidence or arguments suggesting that organic farming should immediately and globally replace all mechanized/chemical-dependent practices.
• "It is imperative for us to modify our land use practices in order to mitigate climate change.": This is a direct and logical inference. The passage establishes that agricultural practices, forestry, and land-use changes collectively contribute a massive portion (about 32%) of global greenhouse gas emissions. Since greenhouse gas emissions drive climate change, altering how we manage land, agriculture, and forests is a necessary step to curb these emissions.
• "There are no technological solutions...": The passage does not discuss technology or state that technological solutions are impossible.
• "Tropical areas are the chief sites of carbon sequestration.": The passage mentions that carbon is stored in the world's peatlands and the Amazon rainforest, but it does not claim that tropical areas are the chief or primary sites of carbon sequestration globally.

Therefore, the most logical and rational inference is that modifying our land-use practices is crucial for mitigating climate change.
