RFK Jr. forgot what makes us healthy Healthy food is not healthy if it destroys the environment that produces it.

Food is not the only thing that determines your health. You also need healthy soil, clean water, and a livable climate.

If the entire nation increases its consumption of meat and dairy, we will not have any of those latter three things.

ICYMI…the most gobsmacking fact from this reporting—>how much land will be needed to produce sustainable aviation fuel

“The maximum amount of land that we’ve converted to cropland in a single year (roughly 1.8 million acres), would have to be quadrupled every year for the next 30 years,” said Limb.

How Lessons from Dermatology Improve Ag+Climate Modeling

Big updates! First, I have a new paper out in the Journal of Environmental Quality demonstrating a technique to improve predictions of soil N2O by individually modeling different "modes" of N2O production. Also, I blogged about the inspiration on my new website! www.ryanackett.com/entries/clas...

Agricultural soil carbon sequestration gets a lot of attention but let’s not forget that the best way to keep carbon in soils is to stop further expansion of agriculture into natural ecosystems.

big paper submission yesterday that I'm incredibly excited about! modeling N2O emissions from ag is notoriously difficult, but with some clever compromises ( high temporal resolution vs high quantitative resolution) we can achieve remarkably accurate results that can drive mitigation efforts!

And I think this phenomenon becomes especially pronounced at the intersections where food and ag cross with climate change and environmentalism. Most of the very strongest and most insane beliefists I’ve encountered live there. In beliefs like, “we can use agriculture to make landscapes healthier than they were before agriculture” and “companies have a financial incentive to protect the environment.”

On some level, I totally understand both of these beliefs. They seem wonderful and incredibly powerful. I mean, if agriculture can make land even healthier than it was before, then we never have to think about what’s the right amount of agriculture! And if companies will do environmentalism, than we never have to deal with our fucked up farm policy!

Fabulous newsletter out by Sarah this morning on the contradictions between beautiful *dreams* of agriculture and the real making of a better food system. These ideas could not be more important, and yet could not be more marginal.

It's a classic win win where cows get grass and meadowlarks get something that's not corn or subdivisions, but biodiversity, land, climate (not just methane, but also nitrous oxide) still suffers.

Most of our most ecologically significant "protected" grasslands are in the production game, and they are DYING, at least compared to the few that aren't. But yeah, conventional corn is worse.

a diagram representing 4 factors that are necessary before a plant disease occurs. Three vertices of a triangle are labeled:
• a susceptible host (the plant),
• the causal agent (pathogen),
• a favorable environment for the pathogen,

Inside the triangle is a circle labeled "time."
