Massive tailwind for GRA?
“The total mass of plastics now exceeds the total mass of all living mammals. That to me is a pretty clear indication that we’ve crossed a boundary. We’re in trouble, but there are things we can do to reverse some of this.”
“Shifting to a circular economy is really important. That means changing materials and products so they can be reused, not wasted.”

Modern food systems have contributed to extensive environmental degradation, resulting in calls for a planetary health diet that dramatically reduces the consumption of animal-source foods. However, animal-source foods provide key micronutrients vital to healthy diets. Planetary boundaries and local contexts must be considered to facilitate regenerative and sustainable livestock production.
Main text
No species has transformed the planet like humans. Much of this transformation has come from the processes involved in producing food for human consumption. Modern food systems—which include the people, places, and practices involved in food production, capture, harvest, processing, transport, retail, consumption, and disposal—are responsible for extensive loss of natural resources and the destruction of ecosystems and biodiversity. But food systems are also essential for human survival. Much of the destructive nature of our food systems has been attributed to our domestication of livestock and the resources this requires. The animal-source foods (ASFs) derived from these livestock also happen to provide us with many of the nutrients we need (Figure 1), access to which varies dramatically around the world. How we provide a growing global population with these essential nutrients while staying within environmental limits is one of our greatest and most pressing challenges.
