 350 survive today

            Why Philosophy?
 Indian poem
 We are limited by what we know
    – Problems can only be defined by what we
    – Solutions can only be developed by what we
   Conser Bio is value ridden unlike ecology
    or pure sciences
Why does conservation matter
         to people?
   Describes how we view the natural world
    and how we may react to conservation
   Found in religious teachings
    – Confucianism
       • Nature interrelated
       • Conserve nature to preserve human
    – Buddhism
       • Loving kindness to nature
       • Still desire, reduce consumption
      Conservation & Religion
   Hinduism
    – Self realization
    – Respect for all life
   Christianity
    – Two views (dominion, connected)
    – Use/steward
   Islam
    – Respect for creation is respect for God
    – Conserve resources
        Human Value Systems
   Utilitarian value
    – Has value because it can be used
       • E.g. forests for timber
    – Anthropocentric view
       • Has value because people can use it
        Utilitarian value
– Values:
  • Goods (timber, fish, water)
  • Services (sewage treatment, air filtration)
  • Information (clouds/weather, crow
    mortality/West Nile, snow
  • Spiritual, cultural and psychological
    (teachings using nature or natural objects
    (large pine tree to the Iroquois people),
    beautiful landscapes that draw in tourists,
    wilderness for canoe enthusiasts.
          Utilitarian value
 Under this view use of nature is good,
  non use a waste
 View prevalent in settling Canada

 Still reflected in our laws

 Both white spruce and yew have uses for
           Intrinsic value
 Has value itself
 People have intrinsic value

 How about other life forms?
           Intrinsic value
 Since living things and ecosystems are
  self organizing some consider they have
  intrinsic value
 If you said that you would pay $1 to save
  the N. Atlantic right whale you agree it
  has intrinsic value
 Changes in philosophy (value systems)
  has led to changes in ethics (moral code)
 Changes result from human experiences
    – Catastrophes
                        Examples: forestry,
    – Tragedies         fishing
    – New knowledge
      History of Western Ethics on
     mid 19th Century
      – Ralph Waldo Emerson, Henry David Thoreau,
        and John Muir
      – Wild places as spiritual/mystical, have intrinsic
        value (transcendental conservation ethic)
      – Natural places need protection even if they
        have no economic value
John Muir worked to protect Yosemite National Park &
parts of the Sierra Nevada mountains.
Resulted in the founding of the Sierra Club
    History of Western Ethics on
 Late 19th Century
