1 Environmental History: An Overview
G. Tyler Miller’s Living in the Environment 13th Edition Chapter 2

2 Chapter 2 Objectives 1. Describe the changes that generally occur during a cultural revolution. Name the shift that the author of your text proposes we are currently undergoing. 2. Briefly describe hunter-gatherer societies, focusing on division of labor and power, the relationship of humans to nature, the impact of their societies on the environment, their use of energy and material resources, and population size. 3. Describe early forms of agriculture. Describe changes that occurred in human population distribution, employment, relationships between societies, environmental impacts on energy and material resources, and the Earth?s carrying capacity as the Agricultural Revolution unfolded.

3 Chapter 2 Objectives 4. Briefly describe the Industrial Revolution, focusing on changes in energy consumption. Describe relationships between energy consumption and the production and consumption of material goods. List the benefits that are distributed to most citizens of industrial societies. 5. Compare hunter-gatherer societies, agricultural societies, and industrial societies, focusing on division of labor and power, the relationship of population to food supply, the relationship of humans to nature, the use of resources (energy and materials) per person, and the environmental impacts. Project how a sustainable-earth society would fit into this analysis.

4 Chapter 2 Objectives 6. Analyze the amount of time over the course of history that has been used to bring about cultural changes. Include a comparison of the length of time to bring about the Agricultural Revolution and the length of time to bring about the Industrial Revolution. Project an amount of time to bring about a cultural change to an earth-wise society. Suggest modern capabilities that might enable this change to occur. 7. Describe each era of U.S. environmental history, noting the contributions of important people, turning points, and major pieces of environmental legislation.

6 Cultural Changes & the Environment
Timeline 160,000 yrs. – Homo sapiens idaltu 60,000 yrs. – Homo sapiens sapiens 12 – 10,000 yrs. – Agricultural revolution 275 yrs. – Industrial revolution 50 yrs. – Information & Globalization revolution Hunter - Gathers

7 Hunter-Gatherers Collected wild edible plant parts, hunted, fished, and scavenged. Often nomadic… moving with the seasons. Small bands of 50 or fewer Expert knowledge of natural surroundings High infant mortality & death by yrs. Low environmental impact.

9 Agricultural Revolution 10,000 – 12,000 yrs. ago
Gradually settled in agricultural community Domesticated wild plants & animals Cleared small areas of land by cutting trees, other plants and slash & burn cultivation. Often used shifting cultivation Sustainable cultivation learned by trial and error. Environmental impact low but increasing.

10 Industrial-Medical Revolution 275 yrs. ago (1700’s – 1800’s)
Shifts from renewable to nonrenewable Shifts from local handmade goods to machine made large-scale production of goods. Population increased and cities grew. Farming practices, medicine, nutrition and life expectancy grew. Pollution and poor working conditions grew

11 Information & Globalization Revolution 50 years ago and continues…
Using new technologies for rapid access to increased amounts of information Involves all parts of the globe on some level. Techs include: phone, radio, TV, computers, internet, automated databases, and satellites. Still degrades the environment Cultural diversity reduced.
