Transcript and Presenter's Notes

Title: Ecological challenges


1
Ecological challenges
  • The global commons
  • A commons is a shared resource that a group of
    people uses collectively.
  • Preserving our common ecosystem and assuring its
    continued use is a new imperative.

2
Ecological challenges (continued)
  • Sustainable development
  • Development that meets the needs of the present
    without compromising the ability of future
    generations to meet their own needs.
  • Protecting the environment will require economic
    development.
  • Economic development must be accomplished
    sustainably.

3
Ecological challenges (continued)
  • Threats to the Earths ecosystem
  • Water resources
  • Fossil fuels
  • Arable land

4
Ecological challenges (continued)
  • Forces of change
  • The population explosion
  • World poverty
  • Industrialization

5
Ecological challenges (continued)
  • The limits to growth
  • The world resource base is essentially finite, or
    bounded.
  • The Earths rapid population growth, peoples
    rising expectations, and the rapid
    industrialization of less developed countries are
    heading for collision with a fixed barrier.

Deciding How Much Global Warming Is Too Much
  • Under first treaty (1994) addressing global
    warming, 193 countries, including U.S., pledged
    to avoid dangerous human interference w/
    climate
  • Dangerous not defined
  • Kyoto Protocol took effect 2/16/05, requiring
    participating industrialized countries to cut
    emissions
  • But targets and timetable negotiated w/ no
    agreement on what amount of cuts would lead to
    climatic stability
  • President Bush rejected Kyoto Pact in 2001
  • Some experts say that by time clear evidence is
    at hand, calamity later in century will be
    unavoidable
  • Any consensus on climate risks will likely
    intensify pressure on Bush administration to
    shift from current opposition

Deep in the Sahara, BP Tries to Put Dent in
Global Warming
  • Given Kyoto Protocol, companies that will have to
    curb emissions in compliance w/ their countries
    caps scrambling to figure out how to do so wo/
    killing bottom lines
  • Even in U.S., companies looking for solution,
    figuring its only matter of time before they
    also face caps
  • BP and its partners in Algerian natural-gas
    processing plant injecting carbon dioxide back
    one mile underground (geologic storage)
  • Key question will CO2 stay underground or come
    burping back up out of earth?
  • Concept drawing interest because it could curb
    global warming more quickly than switching to
    alternative energy sources or cutting energy use
  • Source Wall Street Journal, 2/4/05

8
Nations Wince at Kyoto Reality
  • Now govts have to figure out how to divvy up
    responsibility for cuts among companies and
    consumers that produce emissions
  • Producing political backlash
  • E.g., Canada pledged to cut emissions to 6 below
    1990 level by 2012
  • But its emissions are increasing 1.5/yr
  • If emissions continue to grow at current rate,
    Kyoto pledge will require cutting emissions to
    35 below what they would have been in 2012 w/ no
    action

Senators Warm Up to Emissions Curbs
  • Republican opposition to greenhouse gas curbs
    is slowly easing, as concerns mount over damage
    from climate change
  • In Alaska, the two Republican senators say they
    are willing to reconsider carbon-dioxide
    regulation after voting against it two years ago
  • According to recent report by GAO, melting sea
    and glacier ice has resulted in severe erosion
    and flooding problems in 86 of Alaskas native
    villages
  • Legislation proposed in Senate would require
    industry to reduce emissions to 2000 levels by
    2010
  • President Bush is opposed to regulation
  • Many politicians arent sure to what extent
    man-made carbon dioxide is contributing to
    climate change, some scientists dispute link

World Business Council for Sustainable Development
  • Goals To encourage high standards of
    environmental management and to promote closer
    cooperation among businesses, governments, and
    other organizations concerned with sustainable
    development.
  • Called for businesses to manufacture and
    distribute products more efficiently, consider
    their lifelong impact, and recycle components.
  • Recommended revising systems of national
    accounting to include the costs of environmental
    damage, and pricing products to reflect their
    full environmental cost.

11
Voluntary business initiatives
  • Life cycle analysis
  • Involves collecting information on the lifelong
    environmental impact of a product, from
    extraction of raw material to manufacturing to
    its distribution, use, and ultimate disposal.
  • Industrial ecology
  • Refers to designing factories and distribution
    systems as if they were self-contained
    ecosystems.
  • Design for disassembly
  • Means that products are designed so that at the
    end of their useful life they can be disassembled
    and recycled.

12
Sustainable Development
  • What does the principle of sustainable
    development mean when practiced at the level of
    an individual business?
  • Select a business with which you are familiar,
    determine what kinds of changes that business
    would need to make in order to operate
    sustainably.
  • Is it possible for a single business to operate
    sustainably, or does sustainable business require
    a coordinated effort by many companies,
    governments, and international agencies?
