Environmental History:
Learning from the Past
Cultural Changes and the
Environment
Human History


Homo sapiens have been
on Earth 160,000 years
Until 12,000 years ago we
were hunter-gatherers,
moving as we needed for
food
Cultural Changes and the
Environment
Three Cultural Changes

Agricultural revolution


Industrial revolution


Began 10-12,000 yrs ago
150 years ago
Information and globalization revolution

50 years ago
Cultural Changes and the
Environment
Three Cultural Changes

Have increased our impact on
environment in several ways




More energy and technology
Increased food production
Expansion of human population
Increase in resource use
Cultural Changes and the
Environment
Hunters-Gatherers

Most of our existence







Collect edible plants, fish, hunt
Lived in small nomadic bands
Worked together to survive
Population grew slowly
Small environmental impact
South Africa: San, Khwe, Sho,
Bushmen, and Basarwa
Australia: Spinifex people
Cultural Changes and the
Environment
Hunters-Gatherers

Small environmental impact
due to:





Understanding of natural
surrounding
Low population
Low resource use
Migration to allow reparation
Lack of technology
Cultural Changes and the
Environment
Agricultural Revolution

Agricultural Revolution


Began 10-12,000 years ago
H-G  settled, agricultural
communities
Plant cultivation developed
 Slash and burn/shifting
cultivation
 Sustainable
 Grew food for subsistence
 Little impact on the
environment-no machinery
1
4
Clearing
and burning
vegetation
2
Allowing
to revegetate
10 to 30 years
3
Planting
Harvesting for
2 to 5 years
Agricultural Revolution
Good News
More food
Supported a larger population
Longer life expectancy
Higher standard of living for
many people
Bad News
Destruction of wildlife habitats
from clearing forests and
grasslands
Killing of wild animals feeding on
grass or crops
Fertile land turned into desert
by livestock overgrazing
Soil eroded streams and lakes
Formation of villages, towns,
and cities
Towns and cities served as
centers for trade, government,
and religion
Towns and cities concentrated
wastes and pollution and
increased spread of diseases
Increase in armed
conflict and slavery
over ownership of land
and water resources
Cultural Changes and the
Environment
Industrial/Medical Revolution

Industrial/Medical
Revolution


Began in England in
1700’s
U.S. in 1800’s
Huge shift in culture
Cultural Changes and the
Environment
Industrial/Medical Revolution

Cultural shifts






Renewable (wood, water)  nonrenewable
Localized goods large scale, machine made
Rural  urban
Increased crop yields/acre w/ farm machinery
Population ↑ sharply
Environmental impact ↑
Trade-Offs
Industrial-Medical Revolution
Good News
Mass production of useful and
affordable products
Higher standard of living for
many
Greatly increased agricultural
production
Bad News
Increased air pollution
Increased water pollution
Increased waste pollution
Soil depletion and degradation
Lower infant mortality
Longer life expectancy
Increased urbanization
Groundwater depletion
Habitat destruction and degradation
Lower rate of population growth
Biodiversity depletion
Cultural Changes and the
Environment
Information and Global Revolution

Information and Global Revolution


1950’s
New technology to gain rapid access to global info
 TV
 Telephone
 Satellites
 Computers
Did You Know?
Trade-Offs
Information-Globalization Revolution
Good News
Bad News
Computer-generated models
and maps of the earth’s
environmental systems
Information overload can cause
confusion and sense of
hopelessness
Remote-sensing satellite
surveys of the world’s
environmental systems
Globalized economy can
increase environmental
degradation by homogenizing
the earth’s surface
Ability to respond to
environmental problems more
effectively and rapidly
Globalized economy
can decrease cultural
diversity
Environmental History of the
United States
4 Eras

The environmental history of the US can be
divided into 4 eras:
 Tribal
 Frontier
 Early conservation
 Environmental
Environmental History of the US
Tribal Era

Tribal Era





Native Americans
10,000 years before
European settlement
Hunter Gatherers
Slash and burn/shifting
cultivation
Small population
Low environmental impact
Environmental History of the US
Frontier Era

Frontier Era




Early 1600’s—European settlement
Frontier environmental worldview—
vast and inexhaustible resources
Tribes and land conquered
Publicprivate land
Government declared frontier
officially closed in 1890
Environmental History of the US
Early Conservation Era
1832-1870

Early Conservation Era




Alarm at resource depletion
Urged part of unspoiled wilderness be protected as
legacy to future generations
Thoreau (Life in the Woods) and other writers addressed
these issues but not taken seriously
Active role of government increases
Environmental change within democracies involves
voicing opinions through elected officials, legislation,
budgeting, and lobbying by special interest groups.

Types of Environmental Laws
Some of the key types of environmental protection laws
in the United States (see Appendix in book):
• Setting pollution standards (e.g, Clean Air Act)
• Cleanup and restoration ("Superfund Act" =
Comprehensive Environmental Response,
Compensation, and Liability Act)
• Screening substances for safety
(e.g., Toxic Substances Control Act)
• Requiring environmental impact assessment
(e.g., National Environmental Policy Act)
• Protecting ecosystems, resources, and species
(e.g., Endangered Species Act)
• Encouraging resource conservation
(e.g., National Energy Act)
Policy in the United States
Primary forces
involved in
making
environmental
policy at the
federal level in
the United States.
Environmental Groups
Various mainstream environmental groups actively
influence environmental policy in the United States
• Nature Conservancy works to evaluate,
purchase, and protect critical habitat;
• Sierra Club works to focus public attention on key
environmental issues, especially with respect to
land management and protection;
• National Wildlife Federation, National
Audubon Society, and World Wildlife Fund
focus attention on wildlife conservation;
Environmental Groups
• Worldwatch Institute serves as a think tank
and research center to compile and communicate
environmental information;
• Greenpeace focuses public attention by activism.
Environmental Groups
• Recently experienced declined
membership and reduced budgets
• “Group of 10" largest U.S.
environmental organizations depend
heavily on corporate donations
• 6,000+ grassroots organizations
address issues of concern to citizens,
focused locally, regionally, or on a
specific issue.
• Anti-environmental groups focus on
weakening or repealing existing
environmental laws.
