Environmental History Learning from the Past
G. Tyler Millers Living in the Environment 14th
Edition Chapter 2
2
What you will learn in this chapter?
  • How hunter-gatherer societies, agricultural
    societies, and industrialized societies impacted
    the environment. What will the impact be of
    todays globalization and information society?
  • What are the major phases in the history of land
    and wildlife conservation, public health, and
    environmental protection in the US.

3
Key Concepts
  • Three Major Revolutionsin Human Culture

U.S. Environmental History
  • Tribal and Frontier Era
  • Early Conservation Era
  • The Environmental Era

Cultural Changes and the Environment
Hunter-Gatherer Culture
  • Hunter-gatherers modern humans (homo sapiens
    sapiens) have existed about the last 60,000
    years. Until 12,000 years ago we were mostly
    hunter-gatherers.
  • Nomadic seasonal movement lived in small
  • who worked together to find food and survive.
  • Usually limited environmental impact very little
    environmental impact because they moved around in
    such small groups.

Life expectancy 30-40 years, needed to
constantly move looking for food, water and
shelter.
5
Hunter-Gatherer Culture
  • Often survived by being experts on the land and
    their natural surroundings.
  • Advanced hunter-gatherers had a greater
    environmental impact with tools and fire.

6
Cultural Changes and the Environment The
Agricultural Revolution
  • Agriculture about 10,000 to 12,000 years ago
    (end of last ice age) agricultural settlements
    began to spring up. Domesticating wild plants and
    animals.
  • Quality of Life people lived longer and better
    lives with a more consistent food supply.
  • Environmental Impact was not large. Their
    dependence on human muscle power and crude tools
    while they cultivated small areas.

7
Slash and Burn Cultivation
8
The Agricultural Revolution Increased Impact on
Environment
  • Slash and Burn did destroy local environment, but
    was usually very small and had a limited impact.
  • Still a problem
  • in some parts
  • of developing
  • World. (Amazon)

Cultural Changes and the Environment The
Industrial-Medical Revolution
  • Industrial Revolution (mid-1700s)
  • began in England and spread to US in the 1800s
  • people lived longer and healthier
  • environmental degradation increased
  • factory towns sprung up, less people needed to
    farm

11
The Industrial-Medical Revolution A shift to
nonrenewable resources
  • A shift took place where humans moved from
    relying on wood and flowing water to a dependence
    on machines run by nonrenewable fossil fuels
    (first coal, then later oil and natural gas)

12
The Industrial-Medical Revolution Dramatic
Increase in Environmental Impact
  • Factory towns grew polluted, noisy and very
    hazardous. (air pollution, water pollution,
    toxics)
  • Coal smoke filled cities.
  • Fossil fuels powered larger farm machines for
    larger farms.

Cultural Changes and the Environment The
Information/Globalization Revolution
  • Information Revolution Since the 1950s we have
    moved towards technologies to share information
    rapidly on a global scale.
  • Global access to information can help us
    understand and respond to environmental problems,
    but can lead to information overload.
  • What will it mean for future environmental
    protections? Global Environmental Problems

Environmental History of the United States The
Tribal Eras
  • Tribal Era Native Americans
  • Native Americans caused some extinctions, but
    generally were low-impact hunter-gather or
    agricultural societies
  • Frontier Environmental Worldview European
    Settlement (1607-1890)
  • Significant impact as wilderness frontier was
    tamed

17
Environmental History of the United States The
Tribal Era, Native Americans
  • During the tribal era (prior to 1600s for last
    10,000 years)
  • 5-10 million people
  • Hunter-gatherers
  • Small agriculture
  • Mostly a deep respect for the land and low
    environmental impact.
  • No land ownership

18
Environmental History of the United States The
Frontier Era
  • 1607-1890 European settlers
  • Viewed continent as having limitless resources
  • Wilderness was to be tamed
  • Urged people to spread across land
  • Frontier CLOSED in 1890

19
