Technological Advances: Debates About the Environment After 1900
Driving Question: What role have technological advancements played in both worsening and mitigating environmental challenges?
Humanity’s impacts on the planet have become so profound that many scholars believe we have entered a new geological epoch, the Anthropocene, in which human activity has become the dominant impact on climate and the environment. There are over 8 billion of us on this planet. Our machines are powered by fuels that emit greenhouse gases that drive climate change. Our patterns of consumption and production are transforming ecosystems and polluting the Earth’s air, land, and water. At the same time, other species on the planet are rapidly disappearing. Still, the future is unwritten, and you have a part to play in shaping it. What will the world of tomorrow look like? What historical frames can help you prepare for what’s to come?

This activity is under development and will be coming soon!
The Anthropocene
Humans are altering the biosphere (the air, land, and water that makes up the Earth). Some scientists seek to highlight this process by calling the current epoch of geological time the Anthropocene. Do you think we’re living in a new epoch?

Look for answers to these questions:
- What is the other geological name for the Anthropocene?
- What does the graph “Human Influences on Global Temperature” (figure 2.1) illustrate?
- Using the same reference, compare the period between 1880 and 1940 and that between 1940 and 2020. What do you notice?
- What is the current rate of decline in the biodiversity of all sectors of the planet?

Respond to the following questions:
- How does climate change influence human rights? Who is most affected by climate change?
- Are different perspectives on climate change helpful, harmful, or both?
Population Explosion and Environmental Trends, 1880 to the Present
After growing relatively slowly for millennia, the human population has exploded in the last two hundred years, starting with the Industrial Revolution. This article explores how this demographic shift has impacted our climate, in monumental ways.

Look for answers to these questions:
- What have been the general trends in global population over the long span of human history?
- What has been the trend in the past two hundred years in terms of the percentage of people living in cities?
- How has industrialization changed atmospheric CO2 levels, and why does that matter?
- What have been some health effects of fossil fuel use?
After you read
Respond to the following questions:
- The author ends this article by arguing that humanity must cooperate to reduce our impact on the global environment. Do you agree? Why, or why not?
- Given the environmental impact of the Industrial Revolution, do you think this was overall a positive transformation in production and distribution or a negative one? Give reasons for your opinion.
Causation: Environmental Change
You’ve learned a lot about environmental change in this lesson. Think through the causes and consequences of this change, and develop a causal argument.
Environmentalism
Environmentalism is often defined by conflicts: conservation versus preservation, mixed use versus full protection. This article explores the important trends, debates, and people involved in the environmental movement of the nineteenth and twentieth centuries.

Look for answers to these questions:
- What intellectual and artistic movement rejected the Enlightenment idea that humans could control nature?
- Give at least two examples of environmental destruction and/or poor living conditions during the Industrial Revolution.
- Explain the difference between preservation and conservation.
- What is the EPA and why has it been the subject of debate?
- What is the Greenbelt Movement?
After you read
Respond to the following questions:
- Using evidence from this article, explain the causes and effects of environmental changes in the period from 1900 to the present.
- Take some time to consider the “pop quiz” from the beginning of the article. Choose an answer. What evidence from the article challenges or supports your answer? Is your answer different after reading the full article?
- We all live in the same world and breathe the same air. So, is environmental degradation evidence for a “flat” world? Is there anyone who is hurt more by, or benefits more from, the exploitation of the environment? Who?
Conflicts over Natural Resources
Because there are a limited amount of natural resources on Earth, it is perhaps unsurprising that conflicts emerge between nations over the control of those resources. Competition over natural resources has fueled violent conflict throughout the twentieth century and into the current era.

- What are some more recent examples that Spoden uses to illustrate direct military intervention in the name of resource control?

- Use evidence from this article to explain the causes and effects of environmental change from 1900 to the present.
- Do you think conflicts over natural resources will become more or less frequent and violent in the years to come? What are some aspects of the globalization process that might make these conflicts more common and more violent? What are some factors that could potentially help prevent or reduce the violence of conflict over natural resources?
- How is the information in this article useful for responding to the question: “Explain the extent to which new global connections and innovations brought change in different parts of the world from c. 1900 to today.”
