      What is
   Sustainability?
•A process or state of being
that can be maintained at a
certain level indefinitely.
  Environment
Potential for longevity of vital human
ecological support systems.
    • Our planet’s climate (reducing
      global warming by reducing
      carbon output)
    • Agriculture (Food production)
    • Forestry (Maintaining the forests
      for future use)
  Environment
Potential for longevity of vital human
ecological support systems.
•Industry (Clean non-polluting
practices)
•Fisheries (Fish farms)
•Human communities (cities, towns,
rural areas, villages)
This matters because...
        •The choices we make about
        our lifestyles and how we live
        our lives impact all of these
        resources


            •How we use energy
             (gas, oil, water)
            •Where our food comes
             from (local vs. national/
             foreign markets)
  This matters because...
•The choices we make about our lifestyles and how
we live our lives impact all of these resources
   • What we buy (clothing, shoes, technology
      i.e.
      cell phones, iPods, computers, T.V.s
   • How we get around (cars vs. public
      transportation, bikes, walking
       What might happen...
 f we don’t look at how our choices impact
 he earth, and how fast our industry grows,
our society could collapse

     • For example, every 6 months,
        new computers, new cell
        phones,
        new iPods come out and
        everyone wants to update!

     • Another example, the Aztec,
        Incan and Mayan civilizations
        no longer exist because when
        the Spanish came, they
        brought growth (new diseases,
        new foods, new lifestyles, new
        religious practices and new
        economic systems). The local
        communities could not support
To Fix it...
      •What we really need, (or what is
      preferable), is for these systems to
      become productive indefinitely or
      “sustainable”.
         •   Sustainable agriculture (buying
             food from local farmers)
         •   Sustainable economic systems
             (price of food going up, housing too
             expensive, commuting,)
    To Fix it...
•What we really need, (or what is preferable), is for these
systems to become productive indefinitely or “sustainable”.

    •   Preserve sustainable ecosystems (forests,
        animals, plants, ocean life, rain forests) *China
        biggest polluter air pollution affects CA and US
        more than any other place in the world 20% rain
        forests left
    •   Change our lifestyles (our dependency on oil,
        cheap consumer goods (Wal-Mart, Barnes and
        Noble, Starbucks, McDonald’s), instead to
        support local merchants to support strong
        economic communities.
   Sustainability...
•In modern times this term now refers to
discussions around:
   • Climate change
   • Oil dependency and depletion
   • Increased carbon footprints
   • Food production
   • *This word has created movements
      around the world that have helped to
      create international laws to help
      protect the earth (*US refuses to
      sign)
