New data suggest resilience of the planet is now at risk

That is the view of an international team of 18 researchers who provide new evidence of significant changes in four of the nine systems which regulate the resilience of the Earth. One of the systems which has been seriously affected is the nitrogen-phosphorus cycle, which is essential to all life, and is particularly important to both food production and the maintenance of clean water.

“People depend on food, and food production depends on clean water,” says Prof. Elena Bennett from McGill’s School of the Environment who contributed the research on the nitrogen-phosphorus cycle to the study. “This new data shows that our ability both to produce sufficient food in the future and to...
