Answer:
Step-by-step explanation:
Large-scale agriculture can lead to increased atmospheric CO2 due to various practices involved in modern agricultural methods. One of the major contributors to CO2 emissions is the use of fossil fuels to power machinery and equipment such as tractors, harvesters, and irrigation systems used in agriculture. The use of synthetic fertilizers is another factor that contributes to the increase in CO2 emissions. These fertilizers are made from fossil fuels, and their production, transportation, and application to crops require significant amounts of energy. The destruction of natural vegetation for large-scale agriculture, such as deforestation, also contributes to increased CO2 emissions. Plants absorb CO2 from the atmosphere during photosynthesis, but when large areas of vegetation are destroyed, this process is significantly reduced, leading to an increase in atmospheric CO2 levels. Additionally, livestock production also contributes to atmospheric CO2, as the digestive process of cattle and other livestock produces methane, a potent greenhouse gas that contributes to global warming. Overall, large-scale agriculture contributes significantly to the increase in atmospheric CO2 levels, and efforts to mitigate these emissions are necessary to address climate change.
