• ENV 322 Entire Course

• ENV 322 Week 1 Assignment Model Ecosystems

• Gaia Hypothesis. In Chapter 3, the Gaia
  hypothesis is introduced. It addresses two
  hypotheses (1) life, since its inception, has
  greatly affected the planetary environment and
  (2) life has altered Earths environment in ways
  that have allowed life to persist. Do you agree
  with these two hypotheses? Why or why not?

• Model Ecosystems. Review the virtual lab in Model
  Ecosystems. Within this laboratory exercise you
  will categorize various organisms into the
  correct trophic level for five different
  ecosystems. Once completed, you will calculate
  the amount of energy transferred between levels.
  Record your observations.

• ENV 322 Week 1 DQ 1 Gaia Hypothesis

• ENV 322 Week 1 DQ 2 Energy and Food Supplies

• Gaia Hypothesis. In Chapter 3, the Gaia
  hypothesis is introduced. It addresses two
  hypotheses (1) life, since its inception, has
  greatly affected the planetary environment and
  (2) life has altered Earths environment in ways
  that have allowed life to persist. Do you agree
  with these two hypotheses? Why or why not?

• Energy and Food Supplies. The underlying theme of
  this course is energy. As a whole, the global
  society needs to find ways to reduce our energy
  consumption. The food pyramid is a prime example
  of energy transfer within individual ecosystems
  and the biosphere.

• ENV 322 Week 2 DQ 1 Energy Policy

• ENV 322 Week 2 DQ 2 Fossil Fuel Reserves

• Energy Policy. The U.S. Energy Policy is
  currently being reviewed and six main
  recommendations are listed, by Botkin and Keller
  (2011, p. 298). Discuss whether or not each
  recommendation will lead us to a sustainable
  society. Defend your position by discussing the
  benefits and drawbacks.

• Fossil Fuel Reserves. Fossil fuels reserves are
  rapidly depleting in the United States. The oil
  industry is lobbying the United States government
  to grant permission to allow drilling in several
  untapped areas. Select one of the areas below and
  discuss whether you believe that government
  should be allowed to drill for oil.

• ENV 322 Week 2 Outline for Final Paper

• ENV 322 Week 3 Assignment Non-renewable Energy
  Sources

• Final Research Paper Outline. Review the Final
  Research Paper instructions in Week Five of the
  online course or in the Components of Course
  Evaluation section of the course guide. Submit an
  outline of the Final Research Paper.

• Non-renewable Energy Sources. Energy generation
  is an ongoing topic in the United States and
  worldwide. Historically, the nations main energy
  source is fossil fuels. However, nuclear power
  has also contributed throughout history.

• ENV 322 Week 3 DQ 1 Nuclear Energy

• ENV 322 Week 3 DQ 2 Nuclear Waste Disposal

• Nuclear Energy. Based on your readings, do you
  believe that the Unites States should increase
  the use of nuclear energy, a non-renewable
  resource, as a replacement for fossil fuels?
  Defend your answer by discussing the pros and
  cons of nuclear energy.

• Nuclear Waste Disposal. One of the most
  controversial issues when discussing the
  possibility of nuclear power as an energy source
  is the disposal of the spent fuel rods. Yucca
  Mountain, the main proposed repository, has been
  studied for consideration for over ten years.

• ENV 322 Week 4 Assignment How Big Is Your
  Footprint

• ENV 322 Week 4 DQ 1 Alternative Energy Sources
  and Your Local Ecosystem

• How Big is Your Footprint. You will be the energy
  manager for a large business. You will determine
  the mix of solar, wind, coal, and gas that will
  not only provide ample energy, but keep your
  footprint low. You will also attempt to find the
  proper mix of energy at a low cost.

• Alternative Energy Sources and Your Local
  Ecosystem. During this weeks readings, you have
  learned about numerous types of alternative
  energy sources. Each energy source has its
  advantages and disadvantages. Geography often
  determines which of these sources will be the
  most useful in a given area.

• ENV 322 Week 4 DQ 2 Unorthodox Energy Sources

• ENV 322 Week 5 DQ 1 Energy Consumption

• Unorthodox Energy Sources. Throughout the text,
  mainstream energy sources are discussed. One of
  the factors that set humans apart from any other
  species is the ability to think critically and
  develop new and innovative ideas to solve
  environmental problems.

• Energy Consumption. Reducing our energy
  consumption is vital in our quest to preserve the
  environment. The conversion from fossil fuels to
  renewable energy sources will not happen
  overnight. In the meantime, individuals and
  businesses can decrease their dependence on
  fossil fuels

• ENV 322 Week 5 DQ 2 Voluntary vs. Regulatory
  Involvement

• ENV 322 Week 5 Final Paper

• Voluntary vs. Regulatory Involvement. Affluence
  leads to overconsumption and increased waste.
  Governments, industries, and individuals have
  contributed to the lack of environmental
  sustainability. Actions must be taken immediately
  to alter our wasteful ways.

• Focus of the Final Paper
• Energy is defined as the ability to do work. Over
  the duration of this course, you will come to
  differentiate between nonrenewable and renewable
  energy sources.
