3Key Concepts
- Three Major Revolutionsin Human Culture
U.S. Environmental History
4Cultural 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.
5Hunter-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.
6Cultural 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.
7Slash and Burn Cultivation
8The 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)

10Cultural 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
11The 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)
12The 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.

14Cultural 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

16Environmental 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
17Environmental 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
18Environmental 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
19Sections 1 and 2 Review
- What major human cultural changes have taken
place and how have they impacted the environment? - Describe hunter-gather, agricultural, industrial,
and globalization societies. List several trade
offs of each. - When did humans begin to shift away from
renewable resources? - Describe slash and burn techniques.
- How did the impact on the US environment shift
from tribal to frontier times. Describe both
eras.
