We're Running Out of Ancient Sunlight
Where our energy came from, how we're "living beyond our means," and what will happen to our children when we run out

It all starts with sunlight.

Sunlight pours energy on the Earth, and the energy gets converted from one form to another, in an endless cycle of life, death, and renewal. Some of the sunlight got stored underground, which has provided us with a tremendous "savings account" of energy on which we can draw. Our civilization has developed a vast thirst for this energy, as we've built billions and billions of machines large and small that all depend on fuel and electricity.

But our savings are running low, which will most likely make for some very hard times.

In Part I we'll lay out the situation as a foundation for planning our response. Topics in Part I include:

*The history of sunlight in the human story

*How can things look okay yet be so bad?

*The importance of trees--their three vital roles in a renewable environment, and some alarming statistics on what's happening as we cut them down

*The accelerating rate of species extinction as we alter the world and its climate

Let's start at the beginning, with the fuel source that gave life to this planet millions of years ago: sunlight.

We're Made Out of Sunlight

The Sun, the hearth of affection and life, pours burning love on the delighted earth.
--Arthur Rimbaud (1854-1891)

In a very real sense, we're all made out of sunlight.

Sunlight radiating heat, visible light, and ultraviolet light is the source of almost all life on Earth. Everything you see alive around you is there because a plant somewhere was able to capture sunlight and store it. All animals live from these plants, whether directly (as with herbivores) or indirectly (as with carnivores, which eat the herbivores). This is true of mammals, insects, birds, amphibians, reptiles, and bacteria . . . everything living. Every life-form on the surface of this planet is here because a plant was able to gather sunlight and store it, and something else was able to eat that plant and take that sunlight energy in to power its body.

In this way, the abundance or lack of abundance of our human food supply was, until the past few hundred years, largely determined by how much sunlight hit the ground. And for all non-human life- forms on the planet, this is still the case--you can see that many of the areas around the equator that are bathed in sunlight are Wlled with plant and animal life, whereas in the relatively sun-starved polar regions, where sunlight comes in at a thinned-out angle instead of straight-on, there are far fewer living creatures and less diversity among them.

The plant kingdom's method of sunlight storage is quite straightforward. Our atmosphere has billions of tons of carbon in it, most in the form of the gas carbon dioxide, or CO(2). Plants "inhale" this CO(2), and use the energy of sunlight to drive a chemical reaction called photosynthesis in their leaves, which breaks the two atoms of oxygen free from the carbon, producing free carbon (C) and oxygen (O(tm)). The carbon is then used by the plant to manufacture carbohydrates like cellulose and almost all other plant matter--roots, stems, leaves, fruits, and nuts--and the oxygen is "exhaled" as a waste gas by the plant.

Many people I've met believe that plants are made up of soil--that the tree outside your house, for example, is mostly made from the soil in which it grew. That's a common mistake. That tree is mostly made up of one of the gases in our air (carbon dioxide) and water (hydrogen and oxygen). Trees are solidified air and sunlight.

Here's how it works: plant leaves capture sunlight and use that energy to extract carbon as carbon dioxide from the air, combine it with oxygen and hydrogen from water, to form sugars and other complex carbohydrates (carbohydrates are also made of carbon, hydrogen, and oxygen) such as the cellulose that makes up most of the roots, leaves, and trunk.

When you burn wood, the "sunlight energy" is released in the form of light and heat (from the fire). Most of the carbon in the wood reverses the photosynthesis. The small pile of ash you're left with is all the minerals the huge tree had taken from the soil. Everything else was gas from the air: carbon, hydrogen, and oxygen.

Animals, including humans, cannot create tissues directly from sunlight, water, and air, as plants can. Thus the human population of the planet has always been limited by the amount of readily available plant food (and animals-that-eat-plants food). Because of this, from the dawn of humanity (estimated at 200,000 years ago) until about 40,000 years ago, the world probably never held more than about five million human inhabitants. That's fewer people worldwide than live in Detroit today.

I suspect the reason for this low global census is that people in that time ate only wild-growing food. If sunlight fell on a hundred acres of wild lands producing enough food to feed ten people--through edible fruits, vegetables, seeds, and wild animals that ate the plants--then the population density of that forest would stabilize at that level. Studies of all kinds of animal populations show that mammals--including humans--become less fertile and death rates increase when there is not enough food to sustain a local population. This is nature's population control system for every animal species.

Similarly, people's clothing and shelter back then were made out of plants and animal skins which themselves came to life because of "current sunlight," the sunlight that fell on the ground over the few years of their lives. We used the skins of animals and trees to construct clothing and housing.

Extracting more sunlight--from other animals

Something important happened sometime around 40,000 years ago: humans figured out a way to change the patterns of nature so we could get more sunlight/food than other species did. The human food supply was determined by how many deer or rabbits the local forest could support, or the number of edible plants that could be found or grown in good soil. But in areas where the soil was too poor for farming or forest, supporting only scrub brush and grasses, humans discovered that ruminant (grazing) animals like goats, sheep, and cows could eat those plants that we couldn't, and could therefore convert the daily sunlight captured by the scrub and wild plants on that "useless" land into animal flesh, which we could eat. So if we could increase the number of the ruminant animals through herding and domestication, then we could eat more of the recent sunlight they were consuming as grasses and plants. This provided to our ancestors more usable energy, both as work animals and as food animals. And so domestication and herding were born.

Extracting more sunlight--from the land

About this same time in history, we also figured out that we could replace inedible forests with edible crops. Instead of having a plot of land produce only enough food to feed ten people, that same land could now be worked to feed a hundred. The beginning of agriculture is referred to as the Agricultural Revolution, and it began to gather momentum about 10,000 years ago. Because we had discovered and begun to use these two methods (herding and agriculture) to more eficiently convert the sun's energy into human food, our food supply grew. Following the basic laws of nature, because there was more food, there could be more humans, and the human population started growing faster.

Within a few thousand years of that time we also discovered how to extract mineral ores from the Earth, to smelt pure metals from them, and to build tools from these metals. These...

An impressive exploration of historical human culture and its future. 21. Juli 2005
Von Nicholas Soucy - Veröffentlicht auf
Format: Taschenbuch
This is a nearly flawless achievement of creative nonfiction. Hartmann addresses some of the most complex and important issues of human and worldly culture with crisp, enjoyable language.

Thom Hartmann deserves to be recognized as a philosopher because of his clarity of thought and the quality of his observations and arguments.

The various topics are diverse but interrelated. It's difficult to perfectly summarize the contents of thie book, but Hartmann addresses each aspect of life with a sad wisdom and a hopeful optimism.

He addresses anthropocentrism: the tendency humans have to view the rest of the world as valuable only if is can be used or appreciated by people. This type of thinking has been instrumental in our gradual and steady distance from nature in many ways. Hartmann explains why distance from nature is detrimental to the health of the planet, to our bodies and our psychological well-being.

Specifically, Hartmann opens up a relatively unnoticed world of history, in the tradition of Howard Zinn, Derrick Jensen (A Language Older Than Words) and Daniel Quinn (Ishmael). His candor is needed, and his analysis of history and contemporary culture is at once astonishing, necessary and intriguing. Chapter after chapter his words, ideas and citations challenge you to think, to wonder and reconsider human behavior and lies.

He has borrowed some ideas from the aforementioned authors and put them to good use. He is a better writer than Daniel Quinn, who delivers a choppy, amateurish prose in spite of his good intentions. Hartman better converys his ideas, so if you're one of the millions of fans of Ishmael, I guarantee you'll want to buy or rent this book.

The title phrase refers to the fact that the earth's energy and its organisms' lifeforces are fueled by sunlight in some form or another(fossil fuels being ancient sunlight), but this treatise on the history of human culture is infinitely more than a polemic against the oil industry.

It's an exploration of the mistakes that have been made (slavery, deforestation, human and animal exploitation, corruption) and it's a cogent and admirable plea to change the way our political and social leaders govern the world. It's about the cultural stories that pervade our lives, the religions, the assumptions that people should have dominion over the earth's resources and even over other humans.

Covered are such issues as global warming, famine,war, misogyny, art, religiosity, aboriginal lifestyles, agriculture, social opiates (narcotics, alcohol, television, "news", antidepressants, etc).

What truly impressed me about this book was Hartmann's ability to convey his opinions without seeming arrogant or frantic, despite that he is well-educated and obviously concerned. He reminds us how powerful language can be, how it relates to collective memory of historical events and how important it can be to change, even if that evolution is painful or challenging.

I consider this to be an important history text, although his solutions to the problems seem lackluster. What I mean by this is that he correctly identifies human thought (and subsequently human culture) as the culprit. In order to cease the desire for exploitation of other people and of land, it's necessary to do some serious revision in the way we view our relationship with the earth.

So, no, you won't find a checklist of 50 quick things you can do to improve the world; it isn't that simple. Quite frankly, that's what is frustrating about this book and Daniel Quinn's books-- they identify problems clearly, but they know that the solutions are very very difficult and involved.

Read this book with an open mind, and I suspect it will motivate you to change the way you view some aspects of contemporary Western civilization.

One of the most important books of our time 13. Mai 2004
Von Marcus - Veröffentlicht auf
Format: Taschenbuch
Thom Hartmann's "The Last Hours of Ancient Sunlight" is extremely important and cogent, and needs to be read and absorbed by many to ensure the possibility of a future for the human race and all other life on Earth. Divided into three main parts, this book explains in detail where we are, how and why we got here, and what we can do for a brighter future. Very practical, well-researched, comprehensive. I am not aware of a better book on the issues, especially since it not only sets out the realities of our situation (dependence on dwindling oil and clean-water supplies, destruction of forests and plant/animal species, unsustainable population growth, frequent wars, third-world and first-world impoverishment, etc.), but also explains why, fundamentally, human civilization has gotten us into this mess (tracing the causes back thousands of years to the basis of civilization and comparing the recent city-state or nation-state lifestyle to that of the much older tribe), and what we can possibly do to change our course and save our children and their children and the planet they will inherit.
I would give a more detailed or articulate description, but I lent my copy out the day I finished reading it, and several people are already waiting in line to borrow it. If there is a book to buy multiple copies of and give away, this is the best one I have found. Do not let it sit on the bookshelf indefinitely - after you read it, pass it around, from one person to another, making sure it never stays the same place, unread, for long. If you must keep a copy for your own reference, at least buy a second one to pass around to your friends.

Essential impressive reading for mandatory change 28. September 2004
Von Douglas C. Dutting - Veröffentlicht auf
Format: Taschenbuch
I was shocked, entertained, surprised, touched and extremely moved by the contents of this well written eye-opening book. Opposed to other peak-oil subject books this book is not concentrating on the numbers and technical solutions but on our cultural roots and our pathological and illogical behavior as a result. The spiritual part of this book did not bother me at all despite the fact that I don't consider myself as a very spiritual person. I can fully understand his strong arguments to dig into our roots and that we must learn from the point we strayed to the path of superior feeling, materialism, short-term profits, etc... Hartmann delivers his point very well and I recommend this book to all people who think that we can work our way out of this mess we are in by wishfull thinking or technological inventions and to all people who see no way out of it at all (so this are about all people in the industrialized world). We only have to reinvent ourselves and this book shows us the way. Without a doubt one of the top five most important books I have ever read in my life if not the number one. I even think that this book should be read by all children in every school in Europe and America!

Best book on global warming and its consequences 18. September 2006
Von John E. Nelson MD - Veröffentlicht auf
Format: Taschenbuch Verifizierter Kauf
As I was researching global warming for my novel, The Remembering, A Novel of Karma and Global Peril, I read five books on the subject. By far, Harmann's was the most thoughtful and helpful, especially his discussion of how "ancient sunlight" -- oil and other fossil fuels -- engendered the industrial revolution and an unsustainable expansion of human population since the 1880's. Especially useful was his projection of how the human race will fare when oil supplies dwindle during this century along with mass population displacements. There are certain ignore-ant politicians who would benefit from this information and its visionary suggestions on how we might correct our shortsighted errors before it's too late.

This is the one I needed to make myself commit to change 17. Februar 2006
Von Benjamin E. Stone - Veröffentlicht auf
Format: Taschenbuch
Few books in my life have caused me to reconsider my politics or my religion - not to change them so much but to assess why I've held certain beliefs. The new perspective I gained from the read will undoubtedly alter both of these important aspects of my life. This one book impacted me in a way that no other single volume ever has. As soon as my wife is finished reading it, I'll read it again. I'm thinking of buying several copies to circulate among family and friends. Outstanding.
