- GEOG 101 (Section 01) Day 1
2Getting Oriented
- My name is Don Alexander. My office is across the
street at Building 359, Room 215. My local is
2261, and my office hours are noon to 1 on
Mondays and Wednesdays. - Welcome back event for geographers on 12th at
1030 a.m. in Map Room. - How many of you are at VIU for the first time? If
so, if you need a hand figuring anything out,
just let me know. - Free Student Store in Lower Cafeteria on Thursday
9 to 2. - The textbook for this course is available in the
bookstore. There may be used copies of the
previous edition at the bookstore or at the
student union store. Its Environment The
Science Behind the Stories (Canadian edition) by
Jay Withgott, Scott Brennan, and Barbara Murck
(Toronto Pearson Canada, 2013) see
www.pearsoned.ca/highered/ myenvironmentplace/inde
x.html for student support materials. It's a
good book, with lots of illustrations, case
studies, and Canadian examples. Please note that
we will be skipping Chapters 2-4 and going
straight to Chapter 5 for next week.
3Course Focus
- This course will provide an introduction to the
Earth's biophysical systems from an environmental
science/ environmental geography perspective,
with a focus on the increasing impacts of human
beings on these systems, and methods for
analyzing and evaluating human-environment
relationships. - Topics include carrying capacity limits to
growth ecological footprints ecosystems and
energy flows human population growth and
dispersion agriculture and food issues
biodiversity forest management water resources
and fisheries climate change and air pollution
energy use waste management urban
sustainability environmental ethics and policy,
and other concepts and practices relevant to a
sustainable world.
4Getting Oriented
- The course will be a mix of lectures, discussion,
videos, and assignments. - Keep in mind that this course has a waitlist, so
please decide this week if you are going to stay,
or if you have a friend who is registered but is
not here today, tell them to e-mail me right
away. check! - Also read the course outline carefully.... We
will go over some of it today. - If you suffer from a disability of any kind, you
need to register with Disability Services (in
Building 200) and let me know as soon as possible.
5Getting Oriented
- The focus of the course is the global ecological
crisis see http//energyskeptic.com/2011/9-planet
ery-boundaries/ and what we can do to address
it, including what is already being done in a
number of sectors. If you have specific
interests, let me know and I will try to
accommodate them if at all possible. - What are some key environmental issues facing our
planet? What is causing them and how are they
impacting on people and other species? - I would also like to take advantage of whatever
knowledge or previous life experience you have
that is relevant. What can you offer? - Arctic Ice Decline Much Worse Than Expected
- (summer 2012 news story)
6Getting Oriented
- The course will involve two one and half hour
lectures per week, occasional guest speakers,
videos, class discussion, and hands-on
activities. - In addition to the final exam and a mid-term
quiz, there will be two major assignments. For
these, you will choose from the four following
options a life-cycle analysis of an everyday
product, a media analysis of a controversial
environmental issue, a research and writing
project on the ecological and social values
associated with West Linley Valley, and the
development of an environmental education unit to
present in a local elementary or secondary
school. You may also be asked to answer questions
about videos shown, and to participate in a
debate on a key environmental topic. more
instructions soon!

9Chapter 1 will help you understand
- The meaning of the term environment
- The importance of natural resources and
ecosystems - That environmental science and environmental
geography are interdisciplinary - The scientific method and how science operates
- Some pressures facing the global environment
- Sustainability and sustainable development
1-9
10Our Island, Earth -- Overview
- All the things around us with which we interact
- Biotic (living things)
- Animals, plants, forests, soils, etc.
- Abiotic (nonliving things)?
- Continents, oceans, clouds, icecaps
- Our built environment
- Structures, human-created living centres
- Social relationships and institutions
1-10
11Humans
- are altering the natural systems we need for
- resources, health, life-span, wealth, mobility,
leisure - Impacts
- natural systems have been degraded
- long-term threat to health and survival of
ourselves, other species and ecosystems - Environmental science and environmental geography
study - how the natural world works
- how the environment affects humans and vice versa
- Environmental geography gives special emphasis to
how things interrelate in space for instance,
the relationship between pollution and climate
change and health impacts on humans or
ecosystems, or the spread of exotic species and
how they impact on indigenous species.
1-11
12Natural resources vital to human survival
FIGURE 1.1
- Renewable resources
- Perpetually available sunlight, wind, wave
energy - Those that renew themselves over longer periods
timber, water, soil - can be overharvested
- Nonrenewable resources finite supply can be
depleted - Oil, coal, minerals
1-12
13Global human population growth
- More than 7 billion humans
- Why so many humans?
- Agricultural revolution
- Stable food supplies
- Industrial revolution
- Urbanized society powered by fossil fuels
- Sanitation and medicines (decline in death rate)
1-13
FIGURE 1.2
14The Tragedy of the Commons
by Garrett Hardin
- Unregulated exploitation of open access
resources leads to resource depletion --
examples? - Resource users are tempted to increase use until
the resource is gone - Solution?
- Private ownership?
- Voluntary organization to enforce responsible
use? - Governmental regulations?
1-14
15The ecological footprint
developed by Mathis Wackernagel William Rees
- The environmental impact of an individual or
population - Amount of biologically productive land water
required to provide raw materials a population
consumes and absorb the waste produced - Overshoot humans have surpassed the Earths
capacity (the date when humans are said to have
overshot the Earth's carrying capacity is said to
fall earlier and earlier each year and now occurs
August 22nd).
We are using 40 more of the planets resources
than are available on a sustainable basis from
all the land!
1-15
16Environmental science
can help us avoid mistakes made in the
past. The lesson of Easter Island
people annihilated their culture by destroying
their environment. Can we act more wisely to
conserve our planet, or will we drive a
bitumen-filled SUV straight into a cement wall?
1-16
17Environmental science/ geography are
interdisciplinary
- What experts would you need for
- The construction of a new hydroelectric dam
- Environmental review for the Northern Gateway
pipeline - The proposed draining of a wetland to build a new
subdivision - A proposal to permit bear hunting in a national
park - The management of a large oil spill offshore from
a coastal ecosystem
FIGURE 1.3
1-17
18What is an environmental problem?
- The perception of what constitutes a problem
varies between individuals and societies - e.g. DDT, a pesticide
- In developing countries welcome because it kills
malaria-carrying mosquitoes - In developed countries not welcome, due to
health risks
FIGURE 1.4
1-18
19Environmental science is not environmentalism
- Environmental science
- The pursuit of knowledge about the natural world
- Scientists try to remain objective (though
sources of funding can influence questions
studied and conclusions arrived at)? - Environmentalism
- A social movement dedicated to protecting the
natural world, though some environmental
scientists (e.g. David Suzuki, Andrew Weaver)
become environmentalists because they feel the
'facts' demand that we take action as a society
and as a species.
1-19
20- Science
- A systematic process for learning about the world
and testing our understanding of it - A dynamic process of observation, testing, and
discovery - The accumulated body of knowledge that results
from this process - Science is essential for
- Sorting fact from fiction
- Developing solutions to the problems we face
The nature of science
Current controversy over federal government
cancelling evidence-based science projects/
centres and muzzling scientists. This has led to
recent protests (Death of Evidence in Ottawa)
and to editorials in the prestigious science
journal, Nature http//www.nature.com/nature/jour
nal/v487/n7407/full/487271b.html
1-20
21Science Critically examining evidence
- Scientists design tests are ideas supported by
evidence? - Explanations must
- Be testable
- Resist repeated attempts to disprove it
- Eventually consensus results, as with
human-induced climate change. - Accepted ideas can be applied in policy and
management decisions (e.g. prescribed burning)?
1-21
22The scientific method
- A technique for testing ideas with observations
- Assumptions
- The universe works according to unchanging
natural laws - Events arise from causes, and cause other events
- We use our senses and reason to understand
natures laws
FIGURE 1.7
1-22
23The scientific method
- A scientist makes an observation and asks
questions of some phenomenon - The scientist formulates a hypothesis, a
statement that attempts to explain the scientific
question. - The hypothesis is used to generate predictions,
which are specific statements that can be
directly and unequivocally tested. - The test results either support or reject the
hypothesis
FIGURE 1.7
1-23
24There are different ways to test hypotheses
- Natural or correlational tests show real-world
complexity - Cannot show causation
- Manipulative experiments yield the strongest
evidence - Can show causation
- Not always possible to use
FIGURE 1.8
1-24
25The scientific process is part of a larger process
- The scientific process includes peer review,
publication, and debate - A consistently supported hypothesis becomes a
theory, a well-tested and widely accepted
explanation - With enough data, a paradigm shift a change in
the dominant view can occur (examples?)
FIGURE 1.9
1-25
26Sustainability and the future of our world
- Human population growth exacerbates all
environmental problems - The growth rate has slowed, but we still add more
than 200,000 people to the planet each day - Our consumption of resources has risen even
faster than our population growth. - Life has become more pleasant for us so far
- However, rising consumption amplifies the demands
we make on our environment.
1-26
27Ecological footprints are not all equal
- The ecological footprints of countries vary
greatly - Canada uses far more than its equal share of the
worlds resources - Developing countries have much smaller footprints
than developed countries
FIGURE 1.10
1-27
28We face challenges in agriculture
- Expanded food production led to increased
population and consumption - Its one of humanitys greatest achievements, but
at an enormous environmental cost - Nearly half of the planets land surface is used
for agriculture that depends heavily on - chemical fertilizers
- pesticides, and produces
- erosion
- changed natural systems
1-28
29We face challenges in pollution
- Waste products and artificial chemicals used in
farms, industries, and households - Each year, millions of people
die from pollution
1-29
30We face challenges in climate
- Scientists have firmly concluded that humans are
changing the composition of the atmosphere - The Earths surface is warming
- catastrophic decline in Artic sea ice
- melting glaciers
- rising sea levels
- impacted wildlife and crops
- increasingly destructive weather
- Since the Industrial Revolution, atmospheric
carbon dioxide concentrations have risen by 38,
to the highest level in 650,000 years
1-30
31We face challenges in biodiversity
- Human actions have driven many species extinct,
and biodiversity is declining dramatically - We are at the onset of a mass extinction event
FIGURE 1.12
Biodiversity loss may be our biggest
environmental problem once a species is extinct,
it is gone forever
1-31
32The Millennium Ecosystem Assessment
- The most comprehensive scientific assessment of
the condition of the worlds ecological systems,
carried out by the UN - Major findings
- humans have drastically altered ecosystems
- these changes have contributed to human
well-being and economic development, but at a
cost - environmental degradation could get much worse
- degradation can be reversed, but it requires a
lot of work
1-32
33Our energy choices will affect our future
- The lives we live today are due to fossil fuels
- machines
- chemicals
- transportation
- products (e.g. plastics)
- Fossil fuels are a one-time bonanza supplies
will certainly decline - We have used up ½ of the worlds oil supplies
how will we handle this imminent fossil fuel
shortage?
1-33
34Sustainable solutions exist
- We must develop solutions that protect both our
quality of life and the environment - organic agriculture
- new technology
- reduce pollution
- conservation
- recycling
- renewable energy sources
FIGURE 1.13
1-34
35Are things getting better or worse?
- Many people think environmental conditions are
better - Cornucopians Human ingenuity will solve any
problem - Some think things are much worse in the world
- Cassandras predict doom and disaster
- How can you decide who is correct?
- Are the impacts limited to humans, or are other
organisms or systems involved? - Are the proponents thinking in the long or short
term? - Are they considering all costs and benefits?
1-35
36Sustainability a goal for the future
- How can humans live within the planets means?
- Humans cannot exist without functioning natural
systems - Sustainability
- Leaves future generations with a rich and full
Earth - Conserves the Earths natural resources
- Maintains fully functioning ecological systems
- Sustainable development the use of resources to
satisfy current needs without compromising future
availability of resources (ambivalent meaning??)
1-36
37Conclusion
- Environmental science helps us understand our
relationship with the environment and informs our
attempts to solve and prevent problems. - Identifying a problem is the first step in
solving it - Solving environmental problems can move us
towards health, longevity, peace and prosperity - Environmental science and geography can help us
find balanced solutions to environmental problems
