You're right. There are a lot of industry actors making positive changes. It seems the authors are referring to supply chain resiliency in this case, but yes, an abundance of calories and protein grams due to global trade has enormous benefits.

One hidden issue that we will face is the rise of income in low-middle income countries. As their purchasing power increases, they will likely demand more meat and other, more expensive, food options. As we decrease our productivity for the sake of environmental impact, the invisible hand will force the price of food higher. I'm not saying we shouldn't promote regenerative ag, just that this will pose a major problem that we shouldn't ignore.
