BIO 220 Grand Canyon Week 1 Discussion 1
Choose an environmental issue from your textbook, or from your own
personal experience and explain how this environmental issue directly affects
you. What is the role of environmental science in addressing this issue? What
challenges do you believe are the obstacles that would hinder the
recommendations of environmental scientists to address this environmental issue
from being successfully implemented?
BIO 220 Grand Canyon Week 1 Discussion 2
Go to the following website to determine your personal
footprint:.nature.org/greenliving/carboncalculator/index.htm”>.nature.org/greenliving/carboncalculator/index.htm”>http://www.nature.org/greenliving/carboncalculator/index.htm
Report the result of your personal footprint assessment. What factors do you
think had the most effect on your footprint? What can you do to change your
footprint? (Note: For those students using a Screen Reader refer to the
Directions for Screen Reader Users.)
BIO 220 Grand Canyon Week 2 Discussion 1
Select an example of a global biome and an example of an ecosystem
found in that global biome (grassland, forest, desert). What kind of animals
and plants would you expect to make up that ecosystem? Provide one symbiotic
relationship example within your selected ecosystem (such as mutualism,
commensalism, and predator prey).
BIO 220 Grand Canyon Week 2 Discussion 2
View Biome Explorer located in the Topic 2 materials. Choose a
biome and a scenario and explain how conservation genetics (refer to the
lecture notes and textbook for examples) could affect the survival of any of
the species in the scenario. Other than the factors identified in the media
piece, what other factors can you identify that contribute to the growth,
stability, and decline of a species’ population?
BIO 220 Grand Canyon Week 3 Discussion 1
Many people outside of China believe that the country’s effort to
reduce birth rates, through its one-child policy, does not justify its methods.
Do you agree? Can you think of any future, unintended consequences for China as
a result of adopting this policy? Offer an alternative technique (one not
currently used by China) to reduce a country’s fertility rates that you believe
would be less controversial.
BIO 220 Grand Canyon Week 3 Discussion 2
Consider the most recent oil spill in the Gulf of Mexico. Describe
the various mechanisms and pathways that transport toxins to the environment.
Note: Avoid only talking about the oil spill affecting people in Mexico.
BIO 220 Grand Canyon Week 4 Discussion 1
Explain how employing best practices in farming can benefit both
the farmer and the environment. Explain the consequences to both the farmer and
environment for not following sustainable practices.
BIO 220 Grand Canyon Week 4 Discussion 2
Given what you know about genetically modified organisms (GMOs),
identify some of the costs and benefits associated with GMO crops. Which of the
costs and benefits do you find most important? Why? Support your response with
scientific rationale based on concepts you learned from the readings.
BIO 220 Grand Canyon Week 5 Discussion 1
Explain why biodiversity is important for the survival of species,
including humans. How could the destruction of the rainforest, and its biodiversity,
affect people living in the United States?
BIO 220 Grand Canyon Week 5 Discussion 2
How would you balance human preferences—such as aesthetics,
utility, and cost—with biological considerations such as biodiversity,
ecological authenticity, and evolutionary potential? Provide an example of you
would achieve this balance.
BIO 220 Grand Canyon Week 6 Discussion 1
Study the following articles:

.nps.gov/sucr/naturescience/index.htm”>http://www.nps.gov/sucr/naturescience/index.htm
Based on the above articles and your understanding of ecosystems
and populations from this course, explain how volcanoes both destroy and
rejuvenate ecosystems. Make a prediction about how the succession of plants and
animals will unfold as the landscape at Sunset Crater Monument recovers from
the volcanic eruption. What are other geological risks that could have positive
and negative impacts?
BIO 220 Grand Canyon Week 6 Discussion 2
Drilling for oil in the Arctic, off the coast of California, and
in the Gulf of Mexico is a controversial issue. Based on the 2010 British
Petroleum (BP) oil spill in the Gulf of Mexico, provide reasons both for
drilling and against drilling in these locations. Which side of the argument do
you find more persuasive? Why?
BIO 220 Grand Canyon Week 7 Discussion 1
Describe the hydrologic cycle and various methods of water use and
management. What changes might occur in the hydrologic cycle if our climate
were to warm up or cool down significantly?
BIO 220 Grand Canyon Week 7 Discussion 2
Obtain a water quality report from your local municipality. If you
are unable to locate a recent report from your municipality, use a report from
a neighboring municipality. Post a short description of what you found. What
are your thoughts about your tap water after reading the report you obtained?
If you were in charge of your local municipality, and the report indicate
organic impurities within the water supply, what technique(s) for water
management (water pollution control, remediation, or water legislation) would
you employ to address this problem? Predict how the application of the
technique(s) would affect your daily life?
