Synthetic (inorganic based) fertilizers are made in chemical processes, some of which use fossil fuels and contribute to global warming. They also greatly increase the amount of nitrogen entering the global nitrogen cycle which has a serious negative impact on the organization and functioning of the world's ecosystems, including accelerating the loss of biological diversity and decline of coastal marine ecosystems and fisheries.[8] Nitrogen fertilizer releases N2O, a greenhouse gas, into the atmosphere after application.[9] Organic fertilizer nitrogen content is typically lower than synthetic fertilizer.[10]
