Environmental Science 20 – Final Exam Review

Exam Date: Monday Morning (9:00a-12:00pm), January 25th, 2016
I tend to use your other exams to help create the final, and you can expect more questions from
our plant unit on the exam. You are allowed to bring in your Study Cards.
Note: this kind of information is what an educator should be able to provide for you prior to an exam. So
be sure to ask in order to be as successful as possible.

What worked for me in school:
Get a good night sleep the night before.
Don’t cram last minute or stay up late.
Eat well.
Relax and be confident.
It helped for me to tell everyone around me who was stressed that I would get 100% or this exam will be
easy. I typically ended up with similar marks to them but my anxiety levels were far lower.
When studying, recreate an exam environment… your brain will be trained to remember in those
conditions.

Review Questions
Create a short paragraph detailing what you feel is the most important environmental issue
(more renewable energy, protecting biodiversity, climate change, protection of wetlands/riparian areas
etc.) and explain what the issue involves (3), then, practically utilize and detail the steps for making an
environmental policy that would be practical in Moose Jaw in order to make this change happen (7).
Select an important environmental issue. Explain what it is and a practical way to
fix it.
Step of making an environmental policy.
Identify a problem, research causes, envision solution, get organized, access
help/public official, create a bill that may become policy and law.
Explain how the following dimensions of environment that we studied can be connected to one
another to help mitigate pollution and lead to a cleaner, healthier earth -- be specific, the more precise
information and examples you can give, the better. (10 solid points = 20 marks)
(In other words, explain how cleaning the atmosphere through waste reduction/management caused by
the human population can help terrestrial ecosystems... which in turn helps aquatic ecosystems, which
can help atmospheric systems).
Units - connect the following in long answer format
Integrative Nature of ES - variety of sciences and politics of ES
Atmospheric Systems - air quality and climate change
Human Population - energy sources, waste reduction/management
Aquatic Systems - Watersheds and biotic/abiotic factors
Terrestrial Systems - role of plants, intact habitats, soil
Everything that we do has an impact on all of our world’s systems and
sciences. Through the use of fossil fuels rather than clean, renewable energy
sources like wind or hydropower, we release CO2 into our atmosphere. Once in
our atmosphere, carbon dioxide is a greenhouse gas that can increase the
temperature of the planet, shaping the climate both in aquatic and terrestrial
environments. Carbon dioxide is also required for plants to use photosynthesis,
which can increase plant growth worldwide which could be beneficial. However,
since we are changing climates, plants living in certain areas that are adapted to
do so may no longer be able to and either need to move or die out… this may
lower our planet’s biodiversity. As temperatures change, weather patterns will
change which may lead to more extreme weather events such as flooding…
certain aquatic systems, such as riparian areas and wetlands (that are rich with
biodiversity), help absorb flood waters and can help protect terrestrial
ecosystems and human populations. Mitigating the amount of greenhouse gases
released and protecting ecosystems already in place will help to alleviate the
impact of climate change. This can be done through the creation of laws and
policies that limit the amount of greenhouse gases released.
