Livestock production, particularly the raising of cattle, is a significant source of methane and nitrous oxide emissions, which contribute to air pollution and climate change.

Fertilizer use can contribute to air pollution through the release of ammonia, nitrous oxide emissions, and the formation of smog.

Excessive use of nitrogen-based fertilizers is a major contributor to the release of ammonia into the atmosphere, which can lead to air pollution and environmental issues.

Livestock, particularly cattle, emit methane during digestion, which is a potent greenhouse gas contributing to climate change.

Nitrous oxide emissions from agriculture contribute to global warming by trapping heat in the atmosphere.

Food processing can release volatile organic compounds (VOCs), generate particulate matter emissions, and contribute to greenhouse gas emissions, all of which can impact air quality.

Acetone is an example of a volatile organic compound (VOC) that can be emitted during food processing.

Food transportation involves the movement of food products from one place to another, which can contribute to air pollution through exhaust emissions from vehicles, noise pollution, and traffic congestion.

Water transportation is generally considered to have the lowest environmental impact compared to other modes of food transportation.

Food waste prevention refers to the practice of reducing food waste and its associated environmental impacts by minimizing the amount of food that is wasted.

All of the options mentioned are examples of food waste prevention strategies.

Food waste contributes to air pollution by releasing methane and other greenhouse gases during decomposition, generating odor and attracting pests, and contributing to water pollution.

Methane is the primary greenhouse gas emitted from food waste decomposition.

Methane emissions from food waste contribute to global warming by trapping heat in the atmosphere.

Food anaerobic digestion is the process of converting food waste into energy in the absence of oxygen.
