Title: 1. Philosophy


1
1. Philosophy Fundamental Concepts
  • Lecture outline
  • Introduction to Environmental Geology
  • How Geologists Work The Scientific Method
  • Culture and Environmental Awareness
  • Environmental Ethics
  • The Environmental Crisis
  • Fundamental Concepts of Environmental Science

2
Introduction to Environmental Geology
  • Earth formed about 4.6 billion years ago from
    solar nebula
  • Life on earth began about 3 billion years ago
  • Humans evolved during the Pleistocene in the
    last 1.65 million years (0.05 of age of the
    earth)

3
Introduction to Environmental Geology
  • Because of our brain development and anatomical
    build humans have unprecedented capacity to
    alter the environment
  • Provide basic human needs of food, water,
    clothing, shelter
  • Find, extract, and utilize natural resources
  • Evaluate landscapes for human activities
  • Identify, mitigate or eliminate natural hazards
    (floods, landslides, earthquakes, etc.)

4
Introduction to Environmental Geology
  • Geology study of Earth
  • Environmental Geology branch of geology that
    studies human interactions with the environment
  • Environmental opportunities (resources) and
    constraints (hazards) on human activities
  • Human impacts on the environment

5
Introduction to Environmental Geology
  • Environment processes, materials, forms in the
    atmosphere, hydrosphere, geosphere, biosphere
  • Goal recognize potential geological problems in
    advance, then mitigate or eliminate
  • Today field studies (surface, borehole,
    geophysics), lab studies, computers, maps, remote
    sensing
  • In USA Canada greatest exposure to death or
    injury is from.automobile travel

6
Introduction to Environmental Geology
  • Typical projects
  • Water resource development (groundwater surface
    water) protect quantity quality
  • Waste disposal landfills, hazardous waste
  • Hillslope stability avalanches, mass movement
  • Seismic volcanic risk
  • Erosion control water, wind, ice
  • Reclamation of disturbed lands

7
How Geologists Work The Scientific Method
  • Most scientists have a basic curiosity about how
    the world works

8
How Geologists Work The Scientific Method
  • From On the Loose by Jerry Renny Russell
  • One of the best-paying professions is getting
    ahold of pieces of country in your mind, learning
    their smell and their moods, sorting out the
    pieces of a view, deciding what grows there and
    there and why, how many steps that hill will
    take, where this creek winds and where it meets
    the other one below, what elevation timberline is
    now, whether you can walk this reef at low tide
    or have to climb around, which contour lines on a
    map mean better cliffs or mountains. It feels
    good to say I know the Sierra or I know Point
    Reyes. But of course you dontwhat you know
    better is yourself, and Point Reyes and the
    Sierra have helped.

9
How Geologists Work The Scientific Method
  • Thrill of discovery is what excites and motivates
    scientists
  • Goals of science describe, explain, predict
  • Discovery process starts with identifying a
    problem of interest and making observations in
    the field and/or in a laboratory

10
How Geologists Work The Scientific Method
  • Based on those observations, the scientist
    develops one or more questions about those
    observations
  • The scientist suggests one or more possible
    answers hypotheses or multiple hypotheses

11
How Geologists Work The Scientific Method
  • Hypothesis is a statement about how the scientist
    thinks the world works
  • Must be tested by collecting and analyzing data,
    then drawing a conclusion
  • Compare the conclusion with the original
    hypothesis to either accept or reject it
  • Whenever hypothesis is rejected form new set of
    hypotheses and start the process over

12
How Geologists Work The Scientific Method
  • Hypotheses (continued)
  • If a hypothesis survives testing in a variety of
    geographical settings becomes a theory
  • New evidence often disproves an existing
    hypothesis or theory
  • In rare cases, a theory is found to be
    universally proven law
  • Most of work of scientist is to develop and test
    hypotheses, striving to reject current ones and
    develop better ones

13
Culture Environmental Awareness
  • Scientists can develop and test hypotheses but to
    translate scientific understanding into actions
    to prevent, mitigate, eliminate problems requires
    appreciation ofpolitics, culture, ethics,
    religion, and aesthetics
  • Recommended reading Facing Mt, Kenya by Jomo
    Kenyatta
  • Consider how Americans may urge lesser developed
    countries to stop clear-cut logging, dam
    building, water pollution, soil erosion dont
    throw stones in a glass house

14
Culture Environmental Awareness
  • Consider differences among Americans on these
    same issues (and many others)
  • Views promoted by political parties (Republicans,
    Democrats, Libertarians, Greens) on the role of
    government protecting the environment and
    regulating human activities that could affect the
    environment
  • Wealthy vs. impoverished
  • Views on birth control promoted by religious
    leaders
  • Recommended reading Encounters with the
    Archdruid by John McPhee

15
Environmental Ethics
  • Ethics principles, values, moral choices held
    by individuals, families, organizations,
    communities, states, regions, countries
  • Call for development of a Land Ethic
  • philosophical framework for human behavior that
    leads to sustainable economy environment (8
    concepts forthcoming)
  • Understand the earth as a set of ecosystems
    community of organisms interacting with the
    non-living environment in which materials cycle
    and energy flows

16
Environmental Ethics
  • Recommended reading
  • A Sand County Almanac by Aldo Leopold

17
The Environmental Crisis
  • Irreversible environmental degradation of air,
    land, water, plants, wildlife
  • Because of overpopulation, urbanization, and
    industrialization
  • Environmental degradation transcends political
    systems and religious beliefs
  • We have made real progress toward identifying
    problems
  • Most progress in prevention, mitigation,
    elimination of problems has occurred in developed
    countries

18
Fundamental Concepts of Environmental Science
  • 1. Population Growth
  • The number one environmental problem is the
    increase in human population

19
Fundamental Concepts of Environmental Science
  • Population Growth (continued)
  • Current world pop. 6.2 billion
  • Growth birth rate death rate
  • By 2050 at present growth rate 9-10 billion
  • Current growth rate 1.6
  • Doubling time 70/1.6 44 years
  • Ultimately will be controlled be natural
    disasters, mass starvation, ecological degradation

20
Fundamental Concepts of Environmental Science
  • 2. Sustainability
  • Sustainability is the environmental objective
  • Environmental awareness advocacy groups, Earth
    Day
  • Environmental education K-12 universities
  • Environmental legislation to protect critical
    environments or regulate BIG

21
Fundamental Concepts of Environmental Science
  • 3. Systems
  • Understanding the Earths systems and their
    changes is critical to solving environmental
    problems. The earth itself is an open system
    with respect to energy, but essentially a closed
    system with respect to materials

22
Fundamental Concepts of Environmental Science
  • 4. Limitation of Resources
  • The earth is the only suitable habitat we have,
    and its resources are limited

23
Fundamental Concepts of Environmental Science
  • 4. Limitation of Resources (continued)
  • Human impact (population) x
  • (resource use per person) x
  • (environmental impact per unit of resource use)
  • Consider energy use, water use, food
  • Reduce, reuse, recycle

24
Fundamental Concepts of Environmental Science
  • 5. Uniformitarianism
  • The physical processes modifying our landscape
    today have operated throughout much of geologic
    time. However, the magnitude and frequency of
    these processes are subject to natural and
    artificially-induced change

25
Fundamental Concepts of Environmental Science
  • 6. Hazardous Earth Processes
  • There have always been earth processes that are
    hazardous to people. These natural hazards must
    be recognized and avoided where possible and
    their threat to human life and property minimized

26
Fundamental Concepts of Environmental Science
  • 7. Geology as a Basic Environmental Science

A fundamental component of every persons
environment is the geologic component, and
understanding our environment requires a
broad-based comprehension and appreciation of the
earth sciences and related disciplines
27
Fundamental Concepts of Environmental Science
  • 8. Our Obligation to the Future

The effects of land use tend to be cumulative,
and therefore we have an obligation to those who
follow us
