Canada's nitrogen footprint shows great regional variation
Reactive nitrogen emissions contribute to greenhouse gases, as well as air and water pollution. For the first time, researchers from McGill University have calculated Canada's nitrogen footprint (akin to a carbon footprint) at both national and provincial levels. They looked at the three primary sectors that contribute nitrogen to the environment to calculate the annual average nitrogen footprint: Food production and consumption, wastewater treatment, and fossil fuel use. There were some surprises when they analyzed their results.
