Understanding Our Environment
4
Outline
  • Introduction
  • Historical Perspective
  • Pragmatic Resource Conservation
  • Moral and Aesthetic Nature Conservation
  • Modern Environmentalism
  • Global Conservation
  • Current Conditions
  • A Divided World
  • Sustainable Development

5
Introduction
  • Humans have always inhabited both the natural
    world and the social world.
  • Environment
  • Circumstances or conditions that surround an
    organism or groups of organisms.
  • The complex of social or cultural conditions that
    affect an individual or community.

6
Introduction
  • Environmental Science Systematic study of our
    environment, and our proper place in it.
  • Interdisciplinary
  • Integrative
  • Natural Sciences
  • Social Sciences
  • Humanities
  • Mission Oriented

7
Environmental Science
8
HISTORICAL PERSPECTIVE
  • Four Distinct Stages
  • Pragmatic Resource Conservation
  • Moral and Aesthetic Nature Preservation
  • Health and Ecological Damage Concerns
  • Global Environmental Citizenship

9
Pragmatic Resource Conservation
  • George Perkins Marsh - Man and Nature
  • Influenced Theodore Roosevelt and Gifford
    Pinchot.
  • Pragmatic Utilitarian Conservation
  • Greatest good for the greatest number for the
    longest time
  • Multiple Use Policies of USFS.

10
Moral and Aesthetic Nature Preservation
  • John Muir - President Sierra Club
  • Nature deserves to exist for its own sake -
    regardless of degree of usefulness to humans.
    (Biocentric Preservation)

11
Modern Environmentalism
  • Industrial explosion of WW II added new concerns
    to the environmental agenda.
  • Rachel Carson - Silent Spring (1962)
  • Environmental Agenda expanded in 1960s and 70s
    to include
  • Atomic Weapons Testing
  • Fossil Fuel Issues
  • Air and Water Pollution
  • Wilderness Protection

12
Global Concerns
  • Increased technology has greatly expanded
    international communications.
  • Daily events now reported worldwide instead of
    locally or regionally.
  • Global Environmentalism

13
CURRENT CONDITIONS
  • Human Population gt 6 Billion.
  • Adding 85 million people to Earth yearly
  • (211,000 per day!)
  • Food shortages and famines exist in many densely
    populated areas.
  • Water Quantity and Quality Issues
  • While 71 of Earth surface is water, only 3 is
    fresh
  • Crops require- 900 tons of water to produce 1 ton
    grain
  • Several major rivers no longer reach the sea
  • Water quality affected by salts in many areas
  • Aquifers are being depleted-e.g., Ogalala in
    southwestern Great Plains
  • Fossil Fuel Burning
  • Air and Water Pollution
  • Particulate matter, carbon dioxide, nitrous
    oxides, methane, CFCs and more
  • Heavy metals
  • Landscape Destruction
  • Loss of Biodiversity
  • Frequent mention of species going extinct
  • Probably most serious- species going extinct
    before being identified and studied

14
Signs of Hope
  • Progress has been made on many fronts.
  • Population has stabilized in many industrialized
    countries.
  • Incidence of life-threatening diseases has been
    reduced in some countries.
  • Average life expectancy nearly doubled.

15
RICH / POOR A DIVIDED WORLD
  • Poor countries tend to be located in Southern
    Hemisphere.
  • World Bank estimates1.4 billion people live in
    extreme poverty of lt 1 (U.S.) per day.
  • Daily survival necessitates over-harvesting
    resources thus degrading chances of long-term
    sustainability.
  • Poor are often victims and agents of
    environmental degradation.

16
RICH / POOR A DIVIDED WORLD
  • Wealthy countries tend to be located in the
    Northern Hemisphere.
  • About 1/5 of world population live in countries
    with per capita income gt 25,000.00 (U.S.).
  • Poor people exist here as well.
  • Gap between rich and poor continues to increase.
  • Wealthiest 200 people in the world have combined
    wealth of 1 trillion - more than total wealth of
    poorest half (3 billion) of the worlds
    population.

17
Human Development
  • United Nations releases Human Development Index
    (HDI). Based on social factors - ranges from 0.0
    -1.0.
  • Aggregate numbers hide many important inequity
    issues
  • Gender
  • Race

18
A Fair Share of Resources
  • Affluent lifestyles of richer countries consume
    inordinate share of natural resources and
    produces high proportion of pollutants.
  • Takes approximately 450 kg to get an average
    American through the day.
  • US annually throws away 160 million tons of
    garbage.

19
Economic Progress
  • Over the past 50 years, the worlds Gross
    Domestic Product (GDP)increased from 2 Trillion
    to 22 Trillion.
  • Since WW II, average real income in developing
    countries has doubled.
  • BUT
  • General welfare has increased.
  • Worldwide gap between rich and poor has widened.

20
Sustainable Development
  • Meeting the needs of the present without
    compromising the ability of future generations to
    meet their own needs.
  • Benefits must be available to all humans, not
    just sub-set of privileged group.

21
Sustainable Development
  • Many economists see continual economic growth as
    essential in providing more resources to more
    people.
  • Most ecologists view continual growth as
    impossible in the long-run due to non-renewable
    resources and limited ecological waste-disposal
    capabilities.

22
20 20 Compact
  • 1995 United Nations Summit for Social Development
    called all nations to ensure basic needs for
    everyone.
  • 2020 Compact
  • Wealthy countries contribute 20 of aid to
    humanitarian concerns and social development.
  • Developing countries contribute 20 of budget to
    human primary concerns.

23
Indigenous People
  • Indigenous (native) people are often least
    powerful, most neglected people in the world.
  • At least half the worlds 6,000 distinct
    languages are dying.
  • Indigenous homelands may harbor vast percentage
    of worlds biodiversity.
  • Recognizing native land rights and political
    rights may often be a solid ecological safeguard.

24
