From an environmental aspect, food waste leads to a chemical usage such as fertilizers and pesticides, more fuel gets used for transportation, and the more food rots in landfills, the more methane gases created, which is one of the most harmful greenhouse gases that contributes to global warming and climate change. Methane is twenty-three times more powerful than carbon dioxide (CO2). There are two ways in which food waste contributes to greenhouse gas emissions: Decomposition of food waste after being dumped in landfills and the life cycle, which starts from production to consumption (distribution, retail, and consumer waste). Food waste increases the level of greenhouse gas emissions especially with the production of methane, one of the most potent gases. There is an increased need to reduce food waste as it affects the environment in regards to global warming and climate change.
