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?
Why do we study the environment?
History and Purpose
Environmental issues have always been a part of human
historyThere is a lack of historical perspective about environmental history
As a result, we see modern environmental issues in the media without context
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
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?
Three “revolutions” are significant in the development of environmental
science1. Agricultural Revolution
2. Industrial-Medical Revolution3.Information-Globalization Revolution
Agricultural RevolutionGradual 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???
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 civilizationstart to rely on passive solar heating more
Soil conservation practiced in China, India, and Peruerosion a problem in hilly regions
Sewer system in Babylonia, c. 2,000 BCE
Mummy with particulate pollution preserved in lungs
1300s - The Middle AgesPlaque devastates Europe in 1300s development of a public health system
Parliament passes an act forbidding the throwing of filth and garbage into ditches, rivers and waters in the 1300sfirst urban sanitary laws in EnglandEngraving showing dumping (and
“dumping” into waterways in 1300s England
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?
1600s - RenaissanceDeforestation for building and fuel in England, France, Germany in 1600s leave large areas bareSwitch to the use of coal for fuel
1598 - Discovery of the dodo on the island of Mauritius. It was extinct by 1700.
1666 - Japan’s shogun warns of erosion and floodingorders people to plant trees
1690 - William Penn requires settlers in Pennsylvania to preserve 1 acre of trees for every 5 acres they clear
1700s – Enlightenmentbeginning of the industrial-medical
revolution
1760s - Benjamin Franklin and others attempt to regulate waste disposal and water pollution in Philadelphia
1780 - Jeremy Bentham “The question is not, Can they reason? Nor Can they talk? But, Can they suffer?” advocates for animal welfare
Thomas Malthus (1798)Predicted that exponential population growth would
outpace linear food production, which leads to starvation
Quick Think
Industry and medicine are considered good things by
most people (and they are!).
Why might these two things contribute to environmental
problems?
1800s – Industrial AgeFirst Health Inspectors
1804 - John Pintard, first Health Inspector in U.S. appointed in New York in response to epidemics of yellow fever. From 1810 - 1838,
health inspectors are a branch of the police department with duties including environmental sanitation, vital statistics and law
enforcement.
1827 - James Audubon1827 - John James Audubon begins work on his illustrated book,
Birds of America. His work arouses interest in wildlife conservation

ForestA giant sequoia tree 300

act.

CO2
- Svante August Arrhenius - The Nobel-prize winning chemist was the first to predict global warming from fossil fuel induced CO2 buildup.
1900 - Wild buffalo population
drops to fewer than 40 animals from an estimated 30 million a century beforehand. Most are killed in the years just after the Civil War, when the US
Army hopes to remove the buffalo in order to move Indians onto reservations.
Quick ThinkOn 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?

Quick ThinkAfter many environmental tragedies that harmed
thousands of people, laws were created to help protect people and ensure they had access to safe
water and clean air. Laws were also created to preserve and protect wildlife.

to “do the right thing”?
