Science Friday - How Empire and Environmental Destruction Go Hand-In-Hand

Episode Date: December 16, 2024

“The Burning Earth” examines over 800 years of history to demonstrate how violence against people and the planet are one and the same. Also, the host of the “Hazard NJ” podcast talks about the origins of PFAS “forever chemicals” and their impact on New Jersey residents.How Empire and Environmental Destruction Go Hand-In-HandA new book called The Burning Earth: A History takes on a massive question: How did we get here? “Here” being this point in environmental history and decades deep into the climate crisis. Over the span of 800 years of history, the book connects the dots of how the pursuit of empire, environmental destruction, and human migration led us to this moment in time.SciFri producer Kathleen Davis talks with author Dr. Sunil Amrith, a historian at Yale University. They discuss some common threads that run through human and environmental history, why peace has to be a part of climate action, and what we can learn from understanding the past.Transcripts for each segment will be available after the show airs on sciencefriday.com.

A new book asks a giant question. How did we end up in a climate crisis? The idea that we are outside nature. The idea that technology can solve any problem, the idea that we can insulate ourselves. That idea is always a fiction. It's Monday, December 16th, and you're listening to Science Friday.

I'm SciFRI producer Rasha Iridi. Looking back at over 800 years, a new book called The Burning Earth, A History, connects the dots on how the pursuit of empire environmental destruction, and human migration led us to this point in the climate crisis. SciFri producer Kathleen Davis spoke with the book's author, Dr. Sunil Amrith, a historian at Yale University. Welcome to Science Friday. Thank you for being here. Thanks for having me, Kathleen.

Sunil, how did the idea for this massive book come about? So some of the themes in the Burning Earth I've been writing about teaching for two decades, though that was primarily focused on one part of the world, and that's India and Southeast Asia, which is where I do most of my primary research. So some of these questions, some of these themes have really been with me for a long time. But the question of what made me want to take on the story at the truly epic scale, as I do in the Burning Earth, was a coming together of various things. One was my own children who had 10 and under starting to ask me questions about how we've ended up in a place where the environment around us is in such peril.

And I found that I didn't really have a clear answer for them. And so I thought I'd go away and put my historian hat on and my citizen slash parent hat on. And it's really the synthesis of those two things that produce the burning earth. Okay, let's start at the beginning. So if you had asked me to pinpoint an origin for the climate crisis, I think I would give you an answer something like the Industrial Revolution or something a little bit more recent. But you start us off with the Mongol Empire in the 13th century. Why is this the start of the climate crisis, in your opinion? I think it's the start of a heightened level of environmental transformation. I don't think it becomes the climate crisis until late. But the broader question of when is it that humans,

or some human societies acquired the capability to transform not only their local environments, which human beings have always done, but to amplify and accelerate and spread those environmental transformations. In this case, in the case of the Mongol Empire across most of the Eurasian continent, I thought that would be a moment of not origin, but of acceleration. The way that the Mongol Empire served as this catalyst for environmental transformation actually had to do with the fact that the Mongol Empire was very ecologically aware, if I can use that term, which is to say that its power and its profit actually came from throwing different ecologies together. It was the ability to trade, for example, in goods that were unique to distinctive parts of the world, to distinctive soils and

ecologies, so much that we associate with modern globalization and the seeds of that are there in this earlier moment of empire. So as your book progresses and you go through all these different parts of human history, your book keeps going back to this theme that the climate crisis stems from the idea of setting ourselves free from nature. What do you mean by that? Well, first of all, even today, that is not an idea that would make much sense to most people in the world. world, because it's a luxury that most people in the world do not have to be able to ignore natural limits to what we can be and what we can do. But I do see the beginnings of that idea held initially by those who held wealth and power in the world, a sense that the limits

to human life are starting to be transcended. And some of that is demographic. So there's a massive expansion of life expectancy in Europe if you take the beginning of the 19th century and you look at the end of the 19th century, people are living longer. Many of the most devastating infectious diseases are now understood and can be treated. And there is this sense that some of the enduring limits to human existence, including limits to the accumulation of wealth, are being shattered by technology. And I think with that comes a very powerful idea that shaped how we live in the 20th century. The idea that we are outside nature. The idea that technology, the idea that technology, can solve any problem, the idea that we can insulate ourselves. That idea is always a fiction.

And we see that so clearly with the climate crisis. And yet that fiction shapes institutions. It shapes ideas. It shapes images and visions of the future. You spend a solid part of the book writing about war, especially World Wars 1 and 2. Let's start with the first. Why was the first World War such a turning point in climate history? The First World War, even if it was primarily fought in Europe, was a truly global war in terms of its search for resources. It's been described as the first industrial war, the first carbon-fueled war, and by resources, I mean everything from fertilizer to wheat, to timber, and of course to petroleum. The First World War is the first war in which petroleum is absolutely crucial to military. action. And that was a shift that happened during the war itself. At the beginning of the war,

very few military planners would have thought that oil would be as decisive as it was. By the end of the war, you have allied leaders saying we've essentially floated to victory on a sea of oil, most of which was coming from the U.S. and Mexico at that time. And one of the literal elements at play in World War I is nitrogen. How did the demand for nitrogen shape the outcomes of that war? so profoundly and in a multifaceted way, because of course the two key uses of nitrogen come together in the First World War. One is as fertilizer for food production and the other is in the production of explosives. And it was a few years before the First World War that the so-called Harbour Bosch process to capture nitrogen first was devised and implemented. A lot of that chemical knowledge

is also then in a particularly dark way being used to manufacture the chemical weapons that are used by both sides in subsequent battles during the First World War, and that there is also a sense that it's a war over food and that ultimately one of the big explanations for why the Allied side prevails in the First World War, and in fact the same could be said of a second will come to that, is the access that the Allies have to American, Canadian, and Australian grain. Let's talk about World War II. I was really surprised to learn how famine in Europe created this cascade of events that eventually starve people quite far from there, places like Bengal and Indonesia. How did that happen? The colossal impact of famine in Asia during the Second World War is really one of the less discussed aspects of that conflict. And we're talking about famines that took the lives of millions of people, particularly in India and Bengal.

in Vietnam, in China, and as well as in Indonesia. And it was really the distorting effects of the war economy that brought these disasters about. There certainly were natural triggers, so to speak, in Bengal. It was a cyclone. In Java, it was drought as it was in parts of China. But I don't think one can say that the famines were a direct result of those natural events. It was the breakdown of systems of distribution and supply. It was the deliberate policy of the ruling powers, both the British and India and the Japanese in Vietnam and Java, to divert food supplies to theaters of war, for example, to not provide relief, even when the warning signs were there, that starvation was imminent. But it was also the disruptive effect the war had on everyday social and economic relations,

and the fact that those without land, for example, suffered particularly. I mean, it's not an accident that it was the Bengal famine that was a key case study for the great economist Amati Asen's work on famine in the 1980s, which argued that famine is not necessarily about an absolute shortage of food. It's about the decline in certain social groups' ability to access food. And I think that's very much what you see across Asia at the time. After the break, how understanding the history of the climate crisis helps us make sense of the present and the future? So bringing us to a more modern time, you throughout the book describe this sort of violence as twinning.

Violence against people is violence against the earth where there's genocide, there's ecocide. And we are seeing this play out in places like Ukraine, Lebanon, the Congo, Sudan, of course, in Gaza. How does this idea of twinning help us make sense of this point in time where it just seems like there is so much violence? I think in some ways one of the truly appalling and tragic features of what we're living through in terms of mass violence in the world today is that it's almost as if we'd forgotten war. When we talked about the obstacles to climate progress, for example, a lot of that had to do with the stance that different powerful nations would take about cutting emissions that had to do with perhaps vested interests, the fossil fuel industry.

And in some sense, the fundamental obstacle to any kind of environmental progress, war had never gone anywhere and had never gone away. And it has reasserted itself with a vengeance. At the simplest level, reminding ourselves that warfare has always been a driver of both human suffering and environmental harm is something we need to just keep very firmly in our minds when we think about all of these contemporary wars. I think it can be difficult to focus on the environmental consequence of war because it can feel like that is somehow turning. our attention away from the appalling human suffering that we're seeing all around us. And in fact, I think it does the opposite. I think if we take into account the environmental consequences of our current wars in Gaza, in Ukraine, and so many other parts of the world, what we realize is that the environmental

injuries only prolong the human suffering. There are many estimates that scientists on the ground have made that the damage of these wars is going to be intergenerational. So even when finally peace comes, the task of environmental repair will be a forbidding and a very, very long-term one. So I think that's what twinning does. It reminds us that human suffering and environmental harm very often accelerate together. And it almost sounds like you're saying peace has to be part of climate progress. Is that right? That's a beautiful way of putting it, Kathleen. I would wholeheartedly sign up for that as a key message in the Bernie. earth. I think in some ways war and peace have been issues that have not come up so very much in

cop gatherings and even in just the way in which the climate debate is framed. But without peace, the first year of the conflict in Ukraine generated more emissions than Bangladesh produces in a year. Bangladesh, the country of more than 100 million people, which is more climate vulnerable than most. So what does it mean to talk about environmental justice if we're they're not grappling with the fact that at the very same time, military action is itself a colossal driver of environmental injustice. Throughout your book, you come back to these similar themes of greed, power, and money over and over again. Do you think that the future of our planet will be different? I think the future of our planet could be different. And I think one of the things

that I was very determined to do in the Burning Earth is to reckon with what is a very dark and difficult history of greed and destruction and domination, but at the same time to remind us that that history has never been linear and it's never been unchallenged and that there have been voices that have provided an alternative vision of how we might live more peacefully and thus violently on this earth. They are up against a formidable challenge, but the very fact that, that the environmental movement has grown from almost nothing in the 1970s to what is probably the single cause that mobilizes more people, especially young people than any other, is for me at least a source of hope that we could write a different story. We're in the middle

of this history. I suppose that's the thing about the burning earth. This is not about a closed chapter. This is a book that provides a historical account of a story that we are still writing, that we're still right in the midst of. And that, to me, is a source of hope. So how do we take what we learn in this book and actually funnel it into climate action. Is there a concrete action that you would like to see the world take? I think there are two parts of how I'd answer that. The first is one of the key themes in the Burning Earth is that one thing that has changed very little, whether we're talking about the Mongol Empire we're talking about today,

is that it remains the case that how and what we eat and produce food is fundamental driver of our impact on the planet, including on the climate crisis. and agriculture accounts for about a quarter of all greenhouse gas emissions. I was stunned of all the things I found when I was doing the research for the burning earth. I think the single statistic that has stayed with me is the idea that if the carbon emissions from food waste were a country, they'd be the third largest emitter in the world after the US of China. Wow.

So that's one level, I think. And another is, I think, that taking a historical perspective reminds us that we need joined up thinking. We need to think about the climate crisis and the crisis of biodiversity and the crisis of human inequality, really all as part of the same story. I think we miss things when we start isolate any one of these problems from the others. How can people take the lessons from this book and incorporate them into their day-to-day lives? I think one of the things I have concluded at the end of the process of researching and writing the burning earth is that our actions matter. And I think we need a better reason for rationalizing why they matter. I think it's very easy to say, well,

my recycling more is not going to make a dent in any of the environmental challenges we face. And that might even be true. But I think our actions matter intrinsically. Our actions towards environmental protection matter, first of all, because they make us who we are. They reflect the values that we have about the way we want to live in the world. Second of all, because they bring about a shift in collective consciousness, the more people we have in our communities, in our schools, on our campuses, in our cities, in our countryside who are thinking about a more sustainable future, the more that becomes part of the currency, that becomes part of the ways in which we imagine and craft more hopeful futures. We should be thinking in grand, maybe even cosmic ways,

about shifting towards a more ecological consciousness. And in that sense, I think everything matters. You mentioned at the beginning of our conversation that your kids were an inspiration for this book. You wanted to answer their question of how we got here. What do they make of your answer? Have they read the book? Have you told them about what you found? My daughter, who's seven, was particularly excited that I mentioned Black Pink at the end of the book. Because there are ways in which actually the mobilization of musicians and artists and video game designers and filmmakers

are moving us forward. They're moving us towards a different way of imagining our place in the world. And a whole group of Black Pink fans got together to create a group, which I found very inspiring called K-pop for Planet. And my kids are very taken with that level of action where the enthusiasms of young people come together with causes that matter to all of us. Well, what a lovely place to end off.
