How to Stop Eating the Earth

Rob and Jesse talk with Michael Grunwald, author of the new book We Are Eating the Earth.

Food is a huge climate problem. It’s responsible for somewhere between a quarter and a third of global greenhouse gas emissions, but it concerns a much smaller share of global climate policy. And what policy does exist is often … pretty bad.

On this week’s episode of Shift Key, Rob and Jesse talk with Michael Grunwald, the author of the new book We Are Eating the Earth. It’s a book about land as much as it’s a book about food — because no matter how much energy abundance we ultimately achieve, we’re stuck with the amount of land we’ve got.

Grunwald is a giant of climate journalism and a Heatmap contributor, and he has previously written books about the Florida everglades and the Obama recovery act. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:

Robinson Meyer: How did writing the book change how you, yourself, approached food — or you, yourself, eat? Do you find yourself eating less meat now? Do you find yourself eating less dairy?

Michael Grunwald: I cut out beef pretty early in my reporting. It became really obvious early on that beef is the baddie. I mean, if you’re a vegan, that’s amazing. That’s the best thing you can do from a climate perspective. If you’re vegetarian, that’s also great. But it turns out that cutting out beef is about as good as going vegetarian because vegetarians tend to eat more dairy, and cows are really the problem.
 
Beef is like, use 10 times more land and generate 10 times more emissions than chicken or pork. And yeah, chicken or pork are worse than beans and lentils. But I, like many people are weak. I’m a hypocrite. I feel like this stuff, it’s sort of like organized religion — you have to find the level of hypocrisy that you’re comfortable with. And I couldn’t justify continuing to eat beef while writing a book about how beef is really the problem, and we need to eat less beef and better beef.

But look, you know, our ancestors started eating meat 2 million years ago, and we’re really, I think, kind of hardwired to eat it. That said, I have stuck to it. I write in the book about how I did a bunch of reporting on cattle ranches in Brazil, and I spent two weeks sort of trying to think about how we could have better beef. And I did fall off the wagon during those two weeks because like, steak is delicious. People told me that, you know, Oh, if you’re still eating chicken and pork, after a month, you won’t even miss beef. And they lied. I still miss beef.
 
But look, I do think — and we can talk about this — I know in the climate world it’s become kind of uncool to talk about individual action. There’s this whole spate of stories about like, you know, I’m in the climate movement and I don’t care if you recycle, or veganism isn’t gonna save the world. But I honestly think, first of all, emissions are us. JBS and Donald Trump and McDonald’s are not forcing us to eat all this beef. These are decisions we make. Second of all, that if we do take this seriously as a climate crisis — I mean, it’s true. Policy is going to matter more. Corporate behavior is going to matter a lot. But individual emissions matter, too. And I don’t like the idea of people saying, like, Yeah, this is a horrible crisis, but also your emissions don’t matter.
 
I guess I understand enviros don’t want to sound like scolds. They used to have a bad reputation. But honestly, I think … well, now I think their reputation is for ineffectual rather than scoldy. And I think I liked it better when they were scoldy.

Here’s How Much Money Biden Actually Spent From the IRA

When Congress rescinded unobligated funds from the historic climate law, it inadvertently answered a question climate advocates have been asking for months.

The Biden administration left office without ever disclosing how much of the historic climate funding from the Inflation Reduction Act it had spent.

Politico reached out to every federal agency in November in an attempt to answer that question and could only conclude that it was a “big mystery.” The administration had announced awards for about 67% of the $145.4 billion in grants created by the IRA, the outlet found, but the amount that had been obligated — meaning legally committed and therefore, at least in theory, protected — remained largely unknown.

Don’t Wait! These EV Deals Won’t Last.

Unlike just about every other car sales event, this one has a real — congressionally mandated — end date.

Car salespeople, like all salespeople, love to project a sense of urgency. You know the familiar seasonal rhythm of the TV commercial: Toyotathon is on now — but hurry in, because these deals won’t last. The end of the discount is, of course, an arbitrary deadline invented to juice that month’s sales figures; there’ll be another sale soon.

But in the electric vehicle market there’s about to be a fire sale, and this time it really is a race against the clock.

1. Trump admin expects the Nuclear Regulatory Commission to ‘rubber stamp’ new reactors

The Trump administration is putting pressure on the Nuclear Regulatory Commission to “rubber stamp” all new reactors, Politico reports based on conversations with three people at the May meeting where the expectation was relayed. The directive to the NRC’s top staff came from Adam Blake, a representative of the Department of Government Efficiency, who apparently used the term “rubber stamp” specifically to describe the function of the independent agency. NRC’s “secondary assessment” of the safety of new nuclear projects would be a “foregone conclusion” following approval by the Department of Energy or the Pentagon, NRC officials were made to believe, per Politico.
