Question

using complete sentences, explain how large - scale agriculture leads to increased atmospheric co₂

Explanation:

Large - scale agriculture often involves deforestation for farmland expansion. Trees absorb CO₂, so their removal reduces CO₂ uptake. Machinery used in large - scale farming burns fossil fuels, releasing CO₂. Also, certain agricultural practices like rice paddy cultivation (methane - producing, and methane can be converted to CO₂ in the atmosphere over time) and livestock rearing (enteric fermentation in ruminants, and manure management which can release CO₂ - related compounds) contribute. Soil tillage in large - scale farming can oxidize soil organic matter, releasing CO₂.

Answer:

Large - scale agriculture leads to increased atmospheric CO₂ through multiple means. Deforestation for farmland reduces CO₂ - absorbing trees. Fossil - fuel - burning machinery emits CO₂. Some crops (e.g., rice) and livestock (through enteric fermentation and manure) have CO₂ - related emissions. Soil tillage oxidizes organic matter, releasing CO₂.
