The current food system is not sustainable and is contributing to climate change, biodiversity loss, and social inequality.
We need to transform the food system into one that is based on agroecology, which is a way of farming that works with nature to produce healthy food and regenerate the environment.
Environmental and social scientists recently released a follow-up to the planetary boundary framework called the safe and just Earth system boundaries.
The original planetary boundary framework, first published in 2009 and updated in 2015, focused on understanding the vital biophysical systems — climate, water, nutrients, biodiversity and aerosols — that support human life on Earth.
It quantified the limits of these systems within which human life can be sustained, which equates to "safe" boundaries.
