More from Less

1. For millennia, humanity was trapped in a Malthusian cycle of scarcity and suffering.

That in all old states some such vibration does exist… no reflecting man who considers the subject deeply can well doubt.

Ancient struggles. For nearly all of human history, our prosperity was inextricably linked to our ability to extract resources from the Earth. As populations grew, so did the demand for food, minerals, and land, inevitably leading to resource scarcity. This dynamic created "Malthusian oscillations"—periods of population growth followed by decline due to famine and privation.

Limited progress. Despite human ingenuity in domesticating plants and animals, building cities, and inventing technologies like irrigation, our ability to "take more from the planet" remained severely constrained. Life expectancy was low (around 28.5 years in 1800), and per-capita income saw only a slow crawl over centuries. Humanity was largely at the mercy of nature.

Nature's dominance. Before the late 18th century, humans had not conquered nature; instead, nature held us in check. Our collective biomass was dwarfed by wild animals, and our impact on the planet was limited by our technological capabilities. This era set the stage for the dramatic changes that the Industrial Revolution would soon unleash.

2. The Industrial Era brought unprecedented prosperity but at a devastating environmental cost.

The Industrial Era was a time of startlingly large and fast improvements in human prosperity, but these improvements came at the expense of our planet.

Steam's revolution. The invention of the steam engine in the late 18th century, followed by electricity and internal combustion, fundamentally altered humanity's relationship with the planet. These new power sources, fueled by fossil fuels, enabled us to overcome the limitations of muscle, wind, and water, leading to exponential growth in population and prosperity. This era saw:

• Massive increases in food production through industrial fertilizers (Haber-Bosch process).
• Rapid urbanization and improved public health (e.g., London's fight against cholera).
• Explosive economic growth and rising living standards for average people.

Industrial errors. This progress, however, came with a dark side. The era was marked by profound moral failures and environmental devastation:

• Slavery, child labor, and colonialism exploited human lives and resources.
• Unchecked pollution fouled air and water, leading to health crises (e.g., Donora smog).
• Massive species extinctions occurred due to overhunting and habitat loss (e.g., passenger pigeon, bison, whales).

Jevons' paradox. Economists like William Jevons and Alfred Marshall observed that human wants are insatiable, and technological efficiency often leads to increased overall resource consumption, not less. This "rebound effect" suggested an unavoidable trajectory towards planetary exhaustion, setting the stage for widespread environmental alarm.

3. Early environmentalism predicted doom, but overlooked a surprising shift.

The broad point I want to make is that we know how to succeed with this work.

Alarming predictions. The first Earth Day in 1970 marked the birth of the modern environmental movement, fueled by images like "Earthrise" and events like the Santa Barbara oil spill. Experts warned of imminent catastrophe: mass famines, irreversible ecosystem collapse, and resource exhaustion within decades. Books like "The Population Bomb" and "The Limits to Growth" painted a grim picture of humanity's future.

CRIB strategies. The proposed solutions to this impending crisis coalesced around the acronym CRIB:

• Consume less: A call for degrowth and reduced material consumption.
• Recycle: To reuse materials and reduce demand for virgin resources.
• Impose limits: On population growth (e.g., China's one-child policy) and industrial activity.
• Back to the land: A movement advocating a return to simpler, less technologically intensive lifestyles.

Simon's optimism. Amidst the widespread pessimism, economist Julian Simon challenged these dire forecasts. He argued that human ingenuity, driven by market incentives, would overcome resource scarcities by finding new reserves or developing substitutes. His famous bet with Paul Ehrlich, where Simon won by predicting falling commodity prices, highlighted this contrarian view.

4. Rich nations are now achieving "more from less," decoupling growth from resource use.

The American economy is now experiencing broad and often deep absolute dematerialization.

The great reversal. Contrary to the Malthusian and Jevons' predictions, a profound and unexpected shift has occurred in advanced economies like the United States and the United Kingdom. These nations are now achieving "absolute dematerialization," meaning they are using less of most resources year after year, even as their economies and populations continue to grow.

Evidence of dematerialization:

• Metals: Total US consumption of steel, aluminum, and copper has significantly declined from peak levels.
• Agriculture: Less land, water, and fertilizer are used to produce more crops.
• Building/Wood Products: Timber and paper consumption are post-peak, with sharp declines.
• Energy: Total US energy use and greenhouse gas emissions have decreased, even as GDP rises.

Beyond CRIB. This dematerialization is not primarily due to the CRIB strategies. Societies have not embraced degrowth, recycling is a separate phenomenon, and "back to the land" movements were too small to have a significant impact. Instead, a different set of forces is at play, allowing us to get "more economy" from "less stuff."

5. This dematerialization is driven by four powerful forces: the "Four Horsemen of the Optimist."

When all four are present, we tread more lightly on our planet.

A powerful quartet. The unexpected dematerialization and broader environmental improvements are driven by a synergistic combination of four forces, which the author calls the "Four Horsemen of the Optimist":

• Technological Progress: Innovations, especially digital technologies, enable us to use fewer materials and create more value.
• Capitalism: Competitive markets incentivize companies to reduce costs, including material inputs, to maximize profits.
• Public Awareness: Growing understanding and concern about environmental harms.
• Responsive Government: Governments act on public will, implementing regulations and policies to address externalities and protect shared resources.

Capitalism's role. Profit-seeking companies, driven by intense competition, constantly seek ways to "slim, swap, optimize, and evaporate" their material consumption. Digital tools are particularly effective in this regard, allowing for:

• Slimming: Thinner aluminum cans, lighter car engines.
• Swapping: Natural gas replacing coal, renewable energy replacing fossil fuels.
• Optimizing: Better utilization of assets like railcars, precision agriculture.
• Evaporating: Smartphones replacing numerous single-purpose devices (calculators, cameras, maps).

Government's necessity. While capitalism drives efficiency, it doesn't inherently address negative externalities like pollution or protect vulnerable species. This is where responsive government, informed by public awareness, steps in to impose limits, create markets for pollution (e.g., cap-and-trade), and establish protected areas, ensuring that progress is both prosperous and sustainable.

6. The world is getting better across many human and environmental metrics.

The total number of poor people in the world peaked right at the time of the first Earth Day in 1970, then started to slowly decrease.

A global miracle. Despite widespread pessimism, data reveals an unprecedented improvement in the human condition and the state of nature globally. This "miracle" is most evident in the dramatic reduction of extreme poverty, which has declined by 60% since 1999, with hundreds of millions fewer people living in poverty today than in 1820.

Widespread progress:

• Health: Global life expectancy has surged, and child and maternal mortality rates have collapsed universally.
• Nutrition: Average daily calorie availability has increased in every region, surpassing active adult male requirements.
• Basic Services: Access to improved drinking water and sanitation has expanded significantly worldwide.
• Education: Secondary education enrollment has risen from less than half to over 75% of teenagers globally.

Greener planet. Environmentally, the world is also showing signs of healing. Global terrestrial biomass is increasing, driven by reforestation in rich countries and slowing deforestation elsewhere. Protected land and marine areas are expanding rapidly, safeguarding biodiversity. These improvements demonstrate that economic growth, when guided by the Four Horsemen, can lead to a healthier planet.

7. Progress brings concentration, leading to both superstar firms and growing inequality.

With the invention of the city and its powerful combination of economies of scale coupled to innovation and wealth creation came the great divisions of society.

Urbanization and consolidation. The Four Horsemen also drive a powerful trend of concentration. People are increasingly moving to cities, with the world already 84% urbanized. Economic activity is consolidating into fewer, larger entities:

• Fewer farms produce more crops.
• Fewer factories generate more manufactured goods.
• Economic output is increasingly concentrated in a smaller number of counties and regions.

Winner-take-all markets. This concentration extends to industries, where a few "superstar" firms capture a disproportionate share of sales and profits. This isn't due to declining competition, but rather to technology-fueled competition that rewards firms best able to leverage new innovations and intangible assets. These superstar firms often pay higher wages and are more productive, while other "zombie" firms stagnate.

Rising inequality. The rise of superstar firms and the geographic concentration of economic opportunity contribute to increasing wealth and income inequality. While overall prosperity rises, gains are fastest at the top, leaving many middle-class households in rich countries feeling left behind. This structural shift, rather than unfairness in institutions, is a primary driver of modern inequality.

8. Disconnection and declining social capital are critical challenges in prosperous societies.

If you lose any sense of being part of something bigger, then why should you care about your fellow man?

Eroding bonds. Despite rising prosperity, many rich countries, particularly the United States, are experiencing a worrying decline in "social capital"—the networks of trust and reciprocity among individuals. This "disconnection" manifests as:

• Decreased trust in others and in government.
• A decline in voluntary associations and community engagement ("Bowling Alone").
• Rising political polarization and tribalism.

Deaths of despair. A stark symptom of this disconnection is the alarming rise in "deaths of despair" (suicide, drug overdose, chronic liver disease) among middle-aged white Americans, even during periods of economic growth. This suggests that economic hardship alone doesn't explain the crisis; rather, a loss of community and purpose plays a significant role.

Perceived unfairness. The concentration of economic gains and the disruption of traditional jobs and communities, even if not objectively unfair, can lead to widespread feelings of resentment and alienation. This perceived unfairness, combined with increasing pluralism, can activate authoritarian tendencies, further eroding social cohesion and making effective governance more challenging.

9. Technological progress, especially digital, fuels endless, non-material growth.

The most interesting positive implication of the model is that an economy with a larger total stock of human capital will experience faster growth.

Ideas as fuel. Economist Paul Romer's work highlights that economic growth is fundamentally driven by "ideas"—nonrivalrous and partially excludable "instructions for combining raw materials." Digital tools are the most prolific and versatile "machines for coming up with ideas" ever invented, enabling continuous innovation without being constrained by physical limits.

Digital acceleration:

• Nonrivalry: Software and designs can be used by countless people simultaneously without depletion.
• Decreased Excludability: Digital tools facilitate the rapid spread of innovations, even if not intended by originators (e.g., open-source software, online tutorials).
• Human Capital Growth: Platforms like Duolingo and YouTube provide free, accessible education, rapidly increasing global human capital.

Future dematerialization. This idea-driven growth ensures that dematerialization will continue and accelerate. Future innovations will further reduce material intensity across industries:

• Manufacturing: 3D printing, advanced material science, and AI-driven design will minimize waste and optimize material use.
• Energy: Cheaper renewables, potential nuclear fusion, and AI-optimized grids will reduce reliance on fossil fuels.
• Transportation: Shared, autonomous, and electric vehicles will drastically cut material and fuel consumption.
• Agriculture: Precision agriculture and GMOs will yield more food from less land, water, and fertilizer.

10. To accelerate progress, we must embrace smart policies and informed individual action.

Never doubt that a small group of thoughtful, committed citizens can change the world.

Government's vital role. While capitalism and tech progress drive dematerialization, responsive government is crucial for addressing externalities and social challenges. Key governmental interventions include:

• Carbon Taxes: Implement revenue-neutral carbon taxes to make pollution costly and incentivize low-carbon alternatives.
• Promote Nuclear Energy: Overcome public fear with evidence, as nuclear is a safe, clean, and reliable power source.
• Reduce Pollution: Enforce strict regulations on all forms of pollution, especially plastic waste and industrial emissions.
• Preserve Species/Habitats: Expand protected areas and enforce bans on trade in endangered animal products.
• Promote GMOs: Support genetically modified organisms for their potential to boost yields and nutrition sustainably.
• Fund Basic Research: Invest in early-stage scientific and technical research, especially in energy and materials.
• Promote Markets & Work: Experiment with place-based policies to rediffuse economic opportunity and rebuild social capital in left-behind communities.

Informed citizenry. Ultimately, the public is the most important force for change. Citizens must inform themselves with facts, challenge misinformation, and demand evidence-based policies. This involves:

• Engaged Citizenship: Voting, advocating, and protesting for policies that align with a healthier planet and society.
• Conscious Consumption: Supporting companies committed to decarbonization and clean energy.
• Personal Actions: Reducing individual carbon footprints (e.g., energy-efficient homes, less driving, plant-rich diets) and buying carbon offsets.
• Building Connection: Actively fostering social capital by engaging across tribal lines, volunteering, and finding common ground to combat disconnection and polarization.
