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.

Plant diseases don’t stop at national borders and miles of oceans don’t prevent their spread, either. That’s why plant disease surveillance, improved detection systems, and global predictive disease modeling are necessary to mitigate future disease outbreaks and protect the global food supply, according to a team of researchers in a new commentary published in Proceedings of the National Academy of Sciences.
