Application involving chemical farm inputs poses harm to people and the environment. The fertilizers used in intensive farming increase emissions of greenhouse gases and its overuse is responsible for the highest single share of agriculture’s direct greenhouse gas emissions. Excess fertilizer results in the emission of climate change-causing gas nitrous oxide (N2O), which is some 300 times more potent than carbon dioxide. "The environmental impact of chemical-dependent farming has reached critical levels. Intergovernmental Panel on Climate Change (IPCC) report was the first to detail both the direct and indirect effects farming on climate change
