Fossil Fuels: Humanity’s Liberator (escaping the Malthusian curse via coal, oil, and gas)

[Ed. note: Part II tomorrow by Dr. Goklany will examine how fossil fuels saved nature, not only mankind, given population growth and the increasing demand for energy.]

What was instrumental in powering the grand transformation that began with Industrial Revolution? The answer is fossil fuels that upended a world that was dependent on living nature for virtually its entire well-being–and thus nature’s Malthusian vise.”

For most of history, outside of conflict, human existence was defined by climate, weather, disease, and other natural factors. Virtually everything that humanity depended upon was the recent product of living nature.

What economic historian Edward Wrigley calls “the organic economy” supplied humanity with all its food, fuel, clothing, and skins, and much of its medicine and material products. Living nature also supplied the sustenance for the animals—oxen, horses, donkeys, camels, even elephants—that humans drafted as beasts of burden to transport themselves and their goods, till the soil, and provide mechanical power.

Organic Fuel, Poverty Energy

Food for human beings and feed for animals were then, as now, the direct or indirect product of recent plant photosynthesis. Virtually all fuel was obtained via woody products. Houses were built from logs and other vegetation supplemented by clay, earth, and stones. The few worldly goods humans possessed were also mostly from recent photosynthetic products (e.g., wood, natural fiber, skin, or bone), barring the occasional trinket or luxury good made of some exotic metal or stone.

No wonder that the gods who controlled the weather and rain— Zeus, Jupiter, Indra, Thor—were the mightiest in the pantheons of ancient civilizations.

When climate and weather cooperated, harvests were adequate, hunger was reduced, health improved, more children survived to adulthood, life expectancy increased, and the population grew—until the next epidemic; the next climatic, weather or other natural disaster; or the next war or breakdown of civil order inevitably led to death and disease, disrupted agriculture, or both.

These Malthusian “misery or vice” checks meant that in pre-industrial societies, 30 percent or more of the population died before reaching age 15. Population growth was slight; if populations grew too large, or living standards outstripped subsistence levels for long, these checks brought them back to subsistence levels.

And so age-wise, there was little or no intergenerational progress in the average per­son’s well-being.

Dawn of Progress

The defeat of subsistence living began when mankind developed technologies that would augment or displace the goods received from living nature. Gradually the supply and nutritional quality of food was increased, and population growth rates started to rise, as did living standards and human well-being. The Industrial Revolution accelerated those trends.

With the accumulation of human capital, exchange of ideas, and hard work, mankind started to commandeer more land to meet its needs and develop technologies that, in some cases, amplified Nature’s bounty but, in other cases, bypassed her altogether. These led to higher food production, better health, longer lifespans, and larger populations with better living standards, which then reinforced human capital and the exchange of ideas, which begat yet more and better technologies. Thus was the cycle of progress born and set in motion.

Today, mankind has transcended the Malthusian checks. Population and well-being soared, and our unprecedented well-being continues to improve.

Fossil Fuels, Prosperity Energy

What was instrumental in powering the grand transformation that began with Industrial Revolution? The answer is fossil fuels that upended a world that was dependent on living nature for virtually its entire well-being–and thus nature’s Malthusian vise.

Specifically, fossil fuels have helped give us—and not just the rich amongst us—illumination, which expands our time; machines that preserve our level of energy; better health and longer life expectancies; faster and more voluminous trade in goods and ideas; more rapid communications within a wider network; and a much larger population.

Fossil fuels today are responsible for at least 60 percent of mankind’s food. They also provide 81 percent of mankind’s energy supply, while nature supplies only 10 percent.

Sixty percent of the fiber used globally for clothing and other textiles are synthetic, coming mainly from fossil fuels. Much (thirty percent) of the remaining—so-called natural fiber, relies heavily on fossil fuel–based fertilizers and pesticides.

With respect to materials, although global estimates are unavailable, nature provides only 5 percent of U.S. materials (by weight). But even this 5 percent, just like the remaining 95 percent, cannot be processed, transported and used without energy inputs.

Seen another way, humanity sans coal, oil, or natural gas would be unable to feed itself, and what food there was would be costlier. There would be more hunger. There would be insufficient energy and materials available to sustain the economy at more than a fraction of its current level. Public health would suffer, living standards would plummet, human well-being would be drastically diminished, and the population would crash.

In the absence of the technologies that depend directly or indirectly on fossil fuels, humanity would have had to expand cropland by another 150 percent to meet the current demand for food. Even more land would have had to be annexed to satisfy existing requirements for energy, materials, clothing, and other textiles using nature’s products.

Not only have these fossil fuel–dependent technologies ensured that humanity’s progress and well-being are no longer hostage to nature’s whims, but they saved nature herself from being devastated by the demands of a rapidly expanding and increasingly voracious human population.

Progress today depends on technological change; economic development; trade in goods, services and ideas; and human capital. But technology is the product of ideas, and fossil fuels have been vital for the generation of ideas.

 

Conclusion

Until the last quarter of a millennium, mankind depended on living nature for all its food and clothing, most of its energy, and much of its material and medicines. She dictated mankind’s numbers, well-being, and living standards.

Nature was never constant. She would smile on some, but not on others. Her smiles, always temporary, would inevitably be replaced by frowns. Her Malthusian checks—hunger, famine, disease, or conflict—ensured that there was little or no progress in the human condition. Many people did not even survive into their 20s, populations grew very slowly, and living standards were generally constrained to subsistence levels.

Although they did not initiate the cycle of progress and are imperfect, fossil fuels are critical for maintaining the current level of progress. Ancient na­ture’s bequest to humanity allowed mankind’s dependence on fickle nature to decline and thus become less vulnerable to weather, climate, disease, and other sources of natural disasters. The Malthusian bonds that held mankind and its well-being in check started to stretch, until they were burst asunder.

It may be possible to replace fossil fuels in the future. Nuclear energy is waiting in the wings. Renewable energies, as their high subsidies and mandates attest, are unable to sustain themselves today. Perhaps, with help from fossil fuels, new ideas will foster technologies that will enable a natural transition away from such fuels.

Progress today depends on technological change; economic development; trade in goods, services and ideas; and human capital. But technology is the product of ideas, and fossil fuels have been vital for the generation of ideas.
