|
|
Mechanisation increases fossil fuel use and emits gases such as carbon dioxide or methane.
|
|
|
Soil erosion leads to nutrient depletion of soil and therefore, less vegetation to fix carbon dioxide from the atmosphere in the process of photosynthesis.
|
|
|
Monoculture use leads to a loss of biodiversity when crops are struck with disease.

Detailed explanation-1: -Food system contributions to climate change. Red meat (beef, pork, and lamb) and dairy production together account for nearly half of the greenhouse gas emissions associated with the U.S. food supply chain.
Detailed explanation-2: -Electricity production (30 percent of 2014 greenhouse gas emissions) – Electricity production generates the largest share of greenhouse gas emissions. Approximately 67 percent of our electricity comes from burning fossil fuels, mostly coal and natural gas.
Detailed explanation-3: -Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth’s temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Detailed explanation-4: -Food needs to be grown and processed, transported, distributed, prepared, consumed, and sometimes disposed of. Each of these steps creates greenhouse gases that trap the sun’s heat and contribute to climate change. About a third of all human-caused greenhouse gas emissions is linked to food.
