2. What are some ecological lessons we
can learn from past events?
What events strike a chord with you?
Why?
In the past, individuals could often affect
huge change. Do you think individuals can
have the same impact in today’s world?
Why?

3. Why do we study the
environment?
History and Purpose

4. Environmental issues have always been
a part of human history
There is a lack of historical perspective about environmental
history
As a result, we see modern environmental issues in the
media without context

5. In the absence of history, myths
emerge such as:
•Rachel Carson’s book “Silent Spring” started the environmentalism
movement
•Environmentalism is just an hysterical over-reaction to science and
technology (or “progress”)
•Environmentalism is a passing fad with no serious ideas to offer
•Environmentalism is a substitute for religion
•Environmentalism is anti-business or economic growth

6. What are some ecological lessons we
can learn from past events?
What events strike a chord with you?
Why?
In the past, individuals could often affect
huge change. Do you think individuals can
have the same impact in today’s world?
Why?

7. Three “revolutions” are significant in the
development of environmental science
1.Agricultural Revolution
2.Industrial-Medical Revolution
3.Information-Globalization Revolution

8. Agricultural Revolution
Gradual move from nomadic
lifestyle of hunter-gatherers to
the farming of domesticated
animals and plants
Started about 10,000 years ago
Led to human population growth
Can you explain why???

9. Ancient Times
Air pollution from wood burning, dust, tanneries,
sewage
Water pollution from dumping sewage and
garbage
Deforestation with the rise of Greek and Italian
civilization
start to rely on passive solar heating more
Soil conservation practiced in China, India, and
Peru

c. 2,000 BCE

pollution preserved in lungs

Engraving showing dumping (and “dumping”
into waterways in 1300s England

11. Quick Think
What type of pollution was
recognized early on as being a
threat to human health?
Is this type of pollution still a
problem?

France, Germany in 1600s leave large areas
bare

Can they reason? Nor Can they talk? But,
Can they suffer?” advocates for animal
welfare

14. Thomas Malthus (1798)
Predicted that exponential population growth would outpace
linear food production, which leads to starvation

15. Quick Think
Industry and medicine are
considered good things by most
people (and they are!).
Why might these two things
contribute to environmental
problems?

16. 1800s – Industrial Age

move Indians onto reservations.

32. Quick Think
On the one hand, we have air pollution, the
destruction of entire species, and acid rain.
On the other hand, we have the creation of
national parks, forest reserves, and clubs
dedicated to preserving nature.
Why do you think we can be so split in how we
manage the environment?
Do you think people are still this way?
