(Photo by P. Regoniel in Picable).

Getting 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 10:30 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. It’s 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/index.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.

Course 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.

Getting 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.

Getting Oriented The focus of the course is the global ecological

crisis [see http://energyskeptic.com/2011/9-planetery-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)

Getting 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!]

Chapter 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

Our Island, Earth -- OverviewAll 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 institutions1-10

Humans…• 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

Natural resources: vital to human survival

• 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

FIGURE 1.1

1-12

Global 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)

FIGURE 1.2 1-13

The “Tragedy of the Commons”

• 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?

The “ecological footprint”

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 Earth’s 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 planet’s resources than are available on a sustainable basis from all the land!

developed by Mathis Wackernagel& William Rees

Environmental 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

Environmental 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

the issues

1-17

What 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

Environmental 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

The nature of science 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

1-20

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/journal/v487/n7407/full/487271b.html]

Science: 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

The 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 nature’s laws FIGURE 1.7

1-22

The 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

There are different ways to test hypotheses

Manipulative experiments yield the strongest evidence • Can show causation• Not always possible to use

Natural or correlational tests show real-world complexity• Cannot show causation

FIGURE 1.8

1-24

The 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

Sustainability 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

Ecological footprints are not all equal

The ecological footprints of countries vary greatly

Canada uses far more than its equal share of the world’s resources

Developing countries have much smaller footprints than developed countries

FIGURE 1.10

1-27

We face challenges in agriculture Expanded food production led to increased

population and consumption

It’s one of humanity’s greatest achievements, but at an enormous environmental cost

Nearly half of the planet’s land surface is used for agriculture that depends heavily on

chemical fertilizers pesticides, and produces erosion changed natural systems

1-28

We 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

We face challenges in climate

Scientists have firmly concluded that humans are changing the composition of the atmosphere The Earth’s 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

We 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

Biodiversity loss may be our biggest environmental problem; once a species is extinct, it is gone forever

FIGURE 1.12

1-31

The Millennium Ecosystem Assessment

The most comprehensive scientific assessment of the condition of the world’s 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

Our 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 world’s oil supplies; how will we handle this imminent fossil fuel shortage?

1-33

Sustainable 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

Are 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

Sustainability: a goal for the future

How can humans live within the planet’s means? Humans cannot exist without functioning natural

systems

Sustainability Leaves future generations with a rich and full Earth Conserves the Earth’s 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

Conclusion

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
