1 Chapter 2 Environmental History: Learning from the Past

2 Cultural Changes and the Environment Human History Homo sapiens have been on Earth 160,000 years Homo sapiens have been on Earth 160,000 years Until 12,000 years ago we were hunter-gatherers, moving as we needed for food Until 12,000 years ago we were hunter-gatherers, moving as we needed for food

3 Cultural Changes and the Environment Three Cultural Changes Agricultural revolution Agricultural revolution Began 10-12,000 yrs ago Began 10-12,000 yrs ago Industrial revolution Industrial revolution 150 years ago 150 years ago Information and globalization revolution Information and globalization revolution 50 years ago 50 years ago

4 Cultural Changes and the Environment Three Cultural Changes Have increased our impact on environment in several ways Have increased our impact on environment in several ways More energy and technology More energy and technology Increased food production Increased food production Expansion of human population Expansion of human population Increase in resource use Increase in resource use

5 Cultural Changes and the Environment Hunters-Gatherers Most of our existence Most of our existence Collect edible plants, fish, hunt Collect edible plants, fish, hunt Lived in small nomadic bands Lived in small nomadic bands Worked together to survive Worked together to survive Population grew slowly Population grew slowly Small environmental impact Small environmental impact South Africa: San, Khwe, Sho, Bushmen, and Basarwa South Africa: San, Khwe, Sho, Bushmen, and Basarwa Australia: Australia: Spinifex people

6 Cultural Changes and the Environment Hunters-Gatherers Small environmental impact due to: Small environmental impact due to: Understanding of natural surrounding Understanding of natural surrounding Low population Low population Low resource use Low resource use Migration to allow reparation Migration to allow reparation Lack of technology Lack of technology

7 Cultural Changes and the Environment Agricultural Revolution Agricultural Revolution- Agricultural Revolution- Began 10-12,000 years ago Began 10-12,000 years ago H-G  settled, agricultural communities H-G  settled, agricultural communities Plant cultivation developed Plant cultivation developed Slash and burn/shifting cultivation Slash and burn/shifting cultivation Sustainable Sustainable Grew food for subsistence Grew food for subsistence Little impact on the environment-no machinery Little impact on the environment-no machinery

8 3 Harvesting for 2 to 5 years 1 Clearing and burning vegetation 2 Planting 4 Allowing to revegetate 10 to 30 years

9 Agricultural Revolution Good NewsBad News More food Destruction of wildlife habitats from clearing forests and grasslands Longer life expectancy Fertile land turned into desert by livestock overgrazing Supported a larger population Formation of villages, towns, and cities Towns and cities served as centers for trade, government, and religion Killing of wild animals feeding on grass or crops Soil eroded streams and lakes Increase in armed conflict and slavery over ownership of land and water resources Towns and cities concentrated wastes and pollution and increased spread of diseases Higher standard of living for many people

10 Cultural Changes and the Environment Industrial/Medical Revolution Industrial/Medical Revolution- Industrial/Medical Revolution- Began in England in 1700’s Began in England in 1700’s U.S. in 1800’s U.S. in 1800’s Huge shift in culture Huge shift in culture

11 Cultural Changes and the Environment Industrial/Medical Revolution Cultural shifts Cultural shifts Renewable (wood, water)  nonrenewable Renewable (wood, water)  nonrenewable Localized goods  large scale, machine made Localized goods  large scale, machine made Rural  urban Rural  urban Increased crop yields/acre w/ farm machinery Increased crop yields/acre w/ farm machinery Population ↑ sharply Population ↑ sharply Environmental impact ↑ Environmental impact ↑

12 Industrial-Medical Revolution Trade-Offs Good NewsBad News Mass production of useful and affordable products Increased air pollution Longer life expectancy Soil depletion and degradation Greatly increased agricultural production Increased urbanization Lower rate of population growth Increased water pollution Groundwater depletion Habitat destruction and degradation Higher standard of living for many Lower infant mortality Increased waste pollution Biodiversity depletion

13 Cultural Changes and the Environment Information and Global Revolution Information and Global Revolution- Information and Global Revolution- 1950’s 1950’s New technology to gain rapid access to global info New technology to gain rapid access to global info TV TV Telephone/Cellphone Telephone/Cellphone Satellites Satellites Computers Computers Did You Know? Did You Know? Did You Know? Did You Know?

14 Information-Globalization Revolution Trade-Offs Good NewsBad News Remote-sensing satellite surveys of the world’s environmental systems Ability to respond to environmental problems more effectively and rapidly Globalized economy can increase environmental degradation by homogenizing the earth’s surface Globalized economy can decrease cultural diversity Computer-generated models and maps of the earth’s environmental systems Information overload can cause confusion and sense of hopelessness
