3. How Do I Use This?
In order to navigate through this PowerPoint, all you need to do is use your mouse.
When you see a word with an underline, you can click on it. When you click, it will take you to
a new page, a website, or a movie. Many of the pictures are linked to different places also.
Basically, whenever the mouse arrow turns into a hand, that means that you can click on it
and it will take you somewhere else.
At the bottom of each screen you will see a variety of words, each underlined. ‘Home’ takes
you to the menu of different choices, the second page you encountered when you opened this
product. ‘Back’ takes you to the page you previously visited. Do not use your backspace key,
because it will not take you to the slide you were previously on. Additionally, there are other
places you can get to at the bottom of the page that relate to the topic. For example, on the
Water Pollution page, you can also access Air Pollution and Soil Contamination, two other
kinds of pollution.
If you feel like you have gotten lost, try the Back button or Home. This way you can go to the

4. Greenhouse Gases
Greenhouse gases are the main cause of global warming. They contribute to what is known
as the Greenhouse Effect, which traps heat and keeps the earth warm.
Watch a video on Global Warming
Insensitivity to the Environment
Humans have not been taking care of the environment. Two major factors contributing to
global warming are Pollution and Clear Cutting. Both of these factors are problematic
because of the way we treat our world.
What Causes Global Warming?

5. Greenhouse Gases
Greenhouse gases are the main cause of global warming. Greenhouse gases are naturally
occurring gases, which are necessary for the earth to survive. The problem with them is that
the concentration of them is now too high. Greenhouse gases trap heat in the earth’s
atmosphere, keeping it warm, called the greenhouse effect. If greenhouse gases did not exist,
the earth would be about 33 degrees Celsius cooler, and would not be able to sustain the
environment. Unfortunately, due to many man-made factors, the greenhouse gases are being
produced in abundance, and are trapping too much heat. This is global warming. The three
main greenhouse gases, in order of importance, are: carbon dioxide, methane and
nitrous oxide.
Methane Nitrous OxideCarbon Dioxide
Home Back What Causes Global Warming?

6. Carbon Dioxide (CO2)
Home Back Methane Nitrous Oxide Greenhouse Gases
Carbon dioxide is always present in the atmosphere. It is a
product of plant and animal respiration (breathing),
decaying organic matter, fermentation, forest/grass fires
and oceans. Like the other greenhouse gases, carbon
dioxide traps heat to contribute to global warming. Humans
increase the amount of carbon dioxide through
deforestation, the burning of fossil fuels, and industrial
processes.
The carbon cycle is important to global warming. As we
increase the amount of carbon dioxide in the atmosphere,
we potentially disrupt the carbon cycle. Check out this link
for an animation on how the carbon cycle works.

7. Methane (CH4)
Methane is a naturally occurring gas and the earth’s crust
contains large amounts of it. Methane is produced from
many different sources, including livestock, biomass
burning, landfills and coal mining. Since the 1700s,
human activities have increased the amount of methane
in the atmosphere by about 150%. Methane is the main
component in natural gas, which is a fossil fuel.
Home Back Carbon Dioxide Nitrous Oxide Greenhouse Gases

8. Nitrous Oxide (N20)
Like the other two greenhouse gases, nitrous oxide is a
naturally occurring gas and is required in the
atmosphere. Nitrous oxide is produced primarily from
soil and water denitrification. When nitrous oxide is
produced in this manor, plants absorb it. Approximately
one third of atmospheric nitrous oxide is produced by
humans. It comes mainly from nitrogenous fertilizers
and the burning of fossil fuels.

9. Pollution
Pollution is a huge problem in the world. It takes many forms, and each type of pollution is
extremely harmful to the environment and negatively affects the climates.
There are three main types of pollution that affect the earth and increase global warming.
They are: Air Pollution, Water Pollution and Soil Contamination
Home Back Insensitivity to the Environment What Causes Global Warming?
Air Pollution
Water Pollution
Soil Contamination

10. Air Pollution
Air Pollution is the release of chemicals and particulates
into the atmosphere. Air pollution can appear in a variety of
ways, including smog, acid rain, “holes” in the ozone layer,
and the greenhouse effect. There are general categories of
air pollution: criteria air contaminants (CAC), persistent
organic pollutants (POPs), heavy metals (HMs), and
toxins.
CACs Smog
and acid rain are results of CACs. The
pollutants in this group include Sulphur
Oxides (SOx), Nitrogen Oxides (NOx)
Particulate Matter (PM), Volatile Organic
Compounds (VOC), Carbon Monoxide
(CO) and Ammonia (NH3).
POPs These
pollutants can last in the environment for
very long periods of time, and can easily
travel great distances. They include
industrial chemicals (PCBs), pesticides,
and unintentional contaminants and by-
products (i.e. dioxins and furans)
HMs HMs
are basic metals, such as mercury and
lead. These metals are easily
transported through air and enter the
water and food supply.
Toxins
CACs, POPs and HMs are all included in
toxins, but this category also includes
more pollutants. They are toxic and/or
poisonous to our health and to the
environment. Click here for a list of toxins.
Home Back Pollution Water Pollution Soil Contamination Insensitivity to the Environment

11. Smog
Smog results from air pollution. Smog is created
through a mixture of components, but ground-
level ozone is the main component. Ground-level
ozone is created when nitrogen oxides and
volatile organic compounds interact in the
presence of sunlight. Smog negatively affects our
health and the health of plants and animals.
Smog creates a hazy atmosphere and is difficult
to see through.
Learn how you can individual choices, environmental factors, and different types of land
use affect the pollution in the air through Smog City, an interactive air pollution simulator.

12. Soil Contamination
Like water pollution, soil contamination is caused by
human activity. Contamination results from either liquid
or solid hazardous substances which have been spilled
or buried into the soil. It can also result from air pollution.
When particles are released into the air, they deposit
themselves into the soil when they land. Water pollution
also plays a role in soil contamination. Soil naturally
soaks up water, and when the water is polluted, the soil
that absorbs it also becomes polluted.
Home Back Pollution Air Pollution Water Pollution Insensitivity to the Environment
When soil is contaminated, it negatively affects all organisms that come in contact with it.
Plants can absorb the contamination through their roots, which may cause them to die, or at
the very least, spread the contamination to the animal that eats it. Animals also come into
contact with contaminated soil when they dig or play it in. The contamination may absorb into
their skin, harming their health.

13. Water Pollution
Home Back Pollution Air Pollution Soil Contamination Insensitivity to the Environment
Water pollution can be divided into two groups,
point source, and non-point source.
Point Source
Point source contamination occurs when
pollutants are emitted directly into a body of
water. Oil spills, landfills and leaking gas
storage tanks are examples of point source
contamination.
Non-point Source Non-
point source contamination occurs when
pollutants are indirectly put into the water
system. Fertilizer run-off is an example of non-
point source contamination. The majority of
water pollution comes from non-point source
contamination.
Non-point source contamination is the hardest to control because there is no definite entrance
point. Steps can be taken to ensure that landfills won’t leak into the water stream, or gas storage
tanks are leak-proof, but it is much harder to control rain, which is why fertilizers run off farms.
Nutrients such as nitrates and phosphates are major factors in water pollution. They negatively
affect the environment by over-stimulating growth, which means that aquatic life, especially plants
and algae will grow faster. This causes clogs in waterways, excessive use of dissolved oxygen as
they decompose, and it blocks light to deeper waters. The respiration of fish and other organisms in
the water is adversely affected, causing them to die prematurely and be in danger of becoming
endangered. Pathogens are another form of pollution that directly affect the environment. They
cause aquatic life to become ill, sometimes causing death.

14. Clear Cutting (Deforestation)
Clear cutting is the removal of trees from a given
section of a forest. It has devastating effects on
the environment and is a major factor in global
warming. The main way that it contributes to
global warming is that clear cutting increases the
amount of carbon dioxide (CO2) in the air. Trees
take carbon dioxide and convert it into oxygen,
but when there are few trees, this can’t happen,
and carbon dioxide levels increase. Carbon
dioxide is one of the greenhouse gases, and
therefore traps heat, thus contributing to global
warming.
Deforestation also affects the immediate environment in which the trees were taken from. The
negative changes in the environment include: removal of the forest canopy (which protects life
on the forest floor); the removal of carbon sinks, which will cause CO2 to build up; a loss of
habitat for underground worms, fungi and bacteria which live in the soil and help keep plants
healthy; and an increase in flash flooding due to the fact that precipitation is no longer trapped
and simply runs off the soil.

Sometimes the effects of clear cutting can be reduced through Reforestation.

15. Acid Rain
Acid rain is precipitation that
contains abnormally high levels of
sulfuric and nitric acids. As acid
rain falls, it makes the land and
water it falls into more acidic. For
water, it means that the bodies of
water can no longer support all the
varieties of life that live there. This
may lead to certain species
becoming endangered.

16. Fossil Fuels
Fossil Fuels are naturally occurring substances which are created from decaying organic
matter. Overtime, heat and pressure from inside the earth turned the decayed matter into fuel,
which, when burned creates energy. The three main fossil fuels are coal, oil and natural gas.
Fossil fuels provide about 90% of the world’s energy. We depend on fossil fuels in order to
operate our cars, provide heat and electricity, etc. Unfortunately, fossil fuels are nonrenewable,
and once they are gone, we can’t get them back. Fossil fuels are always being created,
because organic matter is always decaying, but it takes a lot of time for the decayed matter to
turn into fossil fuels. This is why renewable energy is important – there will never be a
shortage of renewable energy.

17. Insensitivity to the Environment
Ever since industrialization, we have been abusing the environment to an extent never seen
before. The environment cannot sustain the changes that have been made to it in the last 300
hundred years. We have begun to take the environment for granted, and are causing it
damage that may not be fixable. Two different human practices, pollution and clear cutting are
major contributors to global warming.
Pollution Clear Cutting
Home Back What Causes Global Warming?

18. Glossary
Denitrification: A process occurring in soil where bacteria break down nitrates to produce
nitrogen gas, which is returned to the atmosphere.
Permafrost: A thick layer of soil beneath the surface that remains frozen throughout the year
Kinetic Energy: Motion. Anything that moves has motion, and therefore has kinetic energy.
Wind and water both have kinetic energy.
Industrialization: creating industry in a society. The Industrial Revolution took place in the 18th
century (1700s) and created pollutants never seen before.
Fermentation: anaerobic conversion of sugar to carbon dioxide by yeast.

19. Social Changes
Everyone needs to do their part to stop global warming, but there are also some changes
that society as a whole needs to make. Not all the social changes are included here, there
are many more. Here is a website that has a lot of information. If you know more solutions,
try and put them into action in your school, in your community, and let your MP know about
the changes that our government should be making.

20. Renewable Energy
Renewable Energy is energy which is always
available. Nonrenewable energy comes from
sources which may become depleted, and
therefore we cannot count on those sources
always being there. Renewable energy comes
from water, wind, biomass and sunlight. To

energy, go to this website. Moving Water

Home Back Social Changes

21. Solar Energy
Solar energy comes from the sun. The sun is a huge source of energy and has been for
billions of years. It gives energy off in the form of radiation. Not all the energy given off by the
sun is available to us. Availability depends on the sun’s location in the sky, and current cloud
conditions. Also, the atmosphere absorbs some of the sun’s energy, which slightly reduces the
amount available to us. But the amount it absorbs is small and leaves plenty left for us to use.
Solar collectors, such as solar panels are designed to capture the energy which the sun gives
off, and change it from radiation into more usable forms such as heat or electricity.
See an animation of solar energy being used to heat water.
SunSolar Panels
Home Back Renewable Energy Bioenergy Wind Energy Water Energy

22. Wind Energy
Wind energy converts kinetic energy produced by the
wind into more useful forms of energy. Wind energy is
a very attractive form of energy because it is pollution-
free and doesn’t produce greenhouse gases or toxic
substances. It is infinitely sustainable because there is
always wind, and is always giving off kinetic energy.
Wind energy has been used for thousands of years.
One of the most common uses of wind energy was to
propel boats across bodies of water. Wind catches the
sails, and propels the boat.
Wind Turbines
Wind turbines are currently used to convert the kinetic energy into mechanical energy or
electricity. Wind turbines are best suited to very windy areas. The speed of the wind is
determined by a number of factors, including the local terrain, density of the air,
temperature, etc. Wind speed increase the higher above ground one goes, so turbines
are usually located on tall towers or in high, open areas. To see wind turbines at work,

23. Biomass Energy (Bioenergy)
Biomass energy is produced when the
chemical energy stored in fuels made from
biomass are released. Biomass is a by-
product of solar energy which has been stored
through the photosynthetic activity of plants.
The CO2 which the plant removed from the
atmosphere is combined with water to
produce biomass. Different types of wastes
which contain biomass are: agricultural waste,
municipal waste, forest waste and food
processing waste. Specific forms of biomass
include wood, straw and manure. Unlike
fossil fuels, which take years to develop,
biomass is always readily available.
Photosynthesis happens on a regular, daily
basis, creating biomass.
Create your own biogas generator with
instructions from this website!
Cows are a great source of manure

Home Back Renewable Energy Water Energy Wind Energy Solar Energy

24. Water Energy (Hydroelectric Energy)
Water energy depends on the kinetic energy of moving
water. As long as there is snow and water to fill rivers,
lakes, streams and oceans, moving water can be a
source of renewable energy. Unfortunately, water
energy can have a negative impact on the environment.
The dams and reservoirs which are built to increase
water energy production can destroy the environment in
which they are placed. The often destroy large areas of
forest and wildlife habitats. The dams can also block the
movement of fish and other organisms, disrupting the
ecosystem.
In order to reduce the negative impact that dams and
reservoirs can have on the environment, the builders of
them need to consider all aspects of the environment
and ecosystem, and develop a system which works with
the environment, not against it.

Home Back Renewable Energy Bioenergy Wind Energy Solar Energy

25. Reforestation (Forest Conservation)
Reforestation is the process of building up areas
which have been subjected to clear cutting.
When forests are cut down, we need to go in
and plant trees in order to allow the forests to re-
grow. Reforestation allows ecosystems the
chance to return to the balance that was
disrupted when the trees in the area were cut
down. Reforestation occasionally occurs on its
own, but that is not always the case. This is why
society needs to plant trees. Companies who
clear cut areas should replant trees, but that
often is not the case. Fortunately, there are
many opportunities for society to plant trees, and
many organizations have days in which they
plant trees.
There are many programs available in which you can participate in tree-planting. Here is a
website which can provide you with the information you will need if you want to tree-plant.
Home Back Social Changes Renewable Energy Public Transportation

26. Public Transportation
One of the easiest ways to reduce pollution is to take
public transportation. Not only is it cost effective, but it’s
a great way to reduce greenhouse gas emissions. If
everyone in the city of Montreal was to take public
transit, walk or bike to work or school, greenhouse gas
emissions produced by cars, trucks and vans would be
vastly reduced. The air would be cleaner, and there
would be fewer smog days.
Every city, not just the major ones, should have an
effective and widely available public transit system.
Many people don’t take public transit because they feel
it takes too long, is too dirty, or is a hassle. In order to
increase the use of public transit, cities need to offer
more frequent buses or metros at peak times during the
day. More workers should be hired to keep the transit
areas, buses and metros clean.
City budget is a problem for a lot of public transportation needs. The city often does not have
enough money to increase the frequency and number of transit vehicles, and may not be able to
afford as many workers as necessary. Governments should be aware of the public’s need and
desire for effective public transportation. This means writing letters to your MP and making your
voice heard.

There are two types of endangered species: Flora and Fauna.
Flora refers to plant life. Fauna refers to animals.
Flora Fauna

Endangered Species are species which exists in small numbers and may
become extinct if they do reproduce and increase their numbers.
Extinction is when a species no longer exists. Well known examples of extinct
species include dinosaurs and the dodo bird.

29. Fauna - Temperate Climate
Here are some examples of animals in danger in this habitat. The list
is way bigger than this, and we should try to preserve their natural
habitat until they will not exist anymore.
Eastern Cougar, Vancouver Island Marmot, Sea Otter, Bowhead Whale,
Right Whale, Beluga Whale (St. Lawrence River, Ungava Bay and
Southeast Baffin Island-Cumberland Sound populations), Wolverine
(Eastern population), etc.
What causes them to become endangered?:
Because of the pollution, Global Warming and the destruction of their natural habitat, a lot of
these animals are in danger. Some of the birds are not flying to the south anymore, because the
weather is hot enougth in the winter in the continental area. Everything is interrelated, it's the cycle
of life. We have to stop the global warming and what causes it, by doing every small step we can
do. We should start by changing our habits at home and at work to save energy and try not to
encourage the big compagnies who are contribuing to the destruction of the natural habitat of the
animals.

32. Fauna - Rainforest Climate
The fauna in the rainforest climate include apes, parrots, tigers, panthers, etc.
The majority of species in this climate are in danger of becoming endangered or extinct
because of the deforestation and clear cutting of their habitat.
Because of the commercial aspect of the wood in the tropical forest, some big companies
are clear cutting a very important part of the tropical forest. By cutting all those trees, they
are also destroying the natural habitat of an intense variety of animals and insects, and
also they are affecting the natural way of living of these living creatures. If a part of the
animal food chain is interruped because an insect, plant or animal doesnt exist anymore,
all of its predator are going to be affected by that. That is a big problem because
everything is related and we are related to this food chain too. Some animals are
contribuing to the preservation of this habitat or are helping some other animals or
insects to live. The destruction of their natural habitat is so intense, that it is impossible to
think of reconstructing it. But, it's time to stop the problem, stop clear cutting and let the
nature grow for a while. But, if nobody stops the big companies who want to make money
with the trees, this situation will just never stop. Their natural habitat will disapear and the
flora and fauna will eventually disappear too.

1- Put your thermostat down of 1°C.
2- Use energy saving light bulbs. It lasts 12 times longer and it uses less energy
to produce more light.
If everyone installed just one energy saving light bulb the CO2 emissions saved would
fill 2 million double decker buses. And if each house installed three energy
saving bulbs, it would save enough energy to run the country's street lights for a
year.*

Don't forget to turn off the lights when you leave a room, and sometimes you
don't really need to have more than one light open at a time. If you are done with
your computer or any other electric object, you should turn it off and unplug it.
Then you will save energy and you will also preserve the length of working life of
your electric object.
Here are more ways to save energy at home.
Home Back Lifestyle Changes Save Energy at Work What Can I Do?

41. Your family can change some things in your home that may help
to preserve the heat, such as ;
• Sealing the windows with a double glazing or with a special winter sealing product.
Because most of the old house have poor heat preserving capacities or old window
frame. So the energy lost is a big problem. What you can do to help is to put a
sealing silicone around the window frame, put a special heat preserving plastic
surface on the window and then the heat will stay in the house and you will save
energy.
• In fact, you should think of every part of your home, which may lose energy because
of heat loss. (Windows, walls and the roof, etc. )You can fill your wall with insulation,
so the insulation will be better.
• If you want to be sure your home is a good energy saver, you should do an energy
check. Some websites can help you to identify some small energy waste in your way
of living. Then you will be sure you are doing everything to preserve and save
energy!
• You can also generate your own energy. By using solar energy or wind energy. You
can also use solar water heating, to produce your hot water! This way to have hot
water is cleaner and is a good way to preserve the environment.

turn it off. If you are the last one, turn everything off, the computers and the
lights in the general area. If you can change your light bulb, change it for an
energy saving light bulb.
• Close the windows and the doors. Then the heat will not leave the room.
• Always close every heat system if you can or reduce the level of heating. Close
the cooling system too. If you want to preserve the freshness of the room close

The Intergovernmental Panel on Climate Change (IPCC), has recently released
a report stating the influence of global warming in the increasing number of tropical
Storms. However, tropical storms vary often in tendency, therefore, no specific linkage
can be made between Global Warming and hurricanes.
• The surfaces of most oceans have warmed up by 0.25-0.5
degree Celsius during the past several decades.
• The IPCC considers that the likely primary cause of the rise in
global mean surface temperatures in the past 50 years is the
increased gas concentration.
• The hurricanes that do occur near the end of the 21st century
are expected to be stronger and have significantly more
intense rainfall than under present day climate conditions. This
expectation is based on an anticipated enhancement of energy
available to the storms due to higher tropical sea surface
temperatures.
Climate change caused by global warming is nonetheless
altering the temperatures among sea waters.

53. Droughts and Global Warming
• Widespread cutting down of trees for fuel reduces
the soil's ability to hold water, drying out the ground,
triggering desertification, and leading to drought.
• Greater evaporation, particularly during summer
and fall, could exacerbate drought conditions and
increase the risk of wildfires.
• The wildlife therefore sees its habitat destroyed.
• The world of agriculture may also be at risk.
Extreme drought, which makes modern agriculture
virtually impossible, is seen by a new study from the
Hadley Centre for Climate Prediction and Research
as possibly affecting about one-third of the planet in
the next century. (

• The effects of drought caused by global warming
is also threatening populations around the world
where clean water is already rare or difficult to
access. This phenomenon will only increase in the
years to come.

54. Clear cutting in Canada
• Clear cutting is not only affecting
the tropical rainforests, it is a
problem that is close to us as well.
• One of Canada’s symbols is
vanishing due to clear cutting. The
Cedar tree which is used by the
native communities to carve their
totem poles is being cut more and
more to increase the revenues of
British Colombia’s coastal logging
industry.
• Canada possess one the greatest
treasure this earth can give. The
Pacific coast holds one-quarter of
the remaining coastal temperate
rainforest in the world. This is the
largest intact tract left on Earth. And
over 50 per cent of these forests
have been logged

56. Why is the rainforest so important for the Earth?
• Tropical rainforests are incredibly rich ecosystems that play a fundamental
role in the basic functioning of the planet.
• Rainforests are home to probably 50 percent of the world's species, making
them an extensive library of biological and genetic resources.
• In addition, rainforests help maintain the climate by regulating atmospheric
gases and stabilizing rainfall, protect against desertification, and provide
numerous other ecological functions.

57. The Impact of Deforestation of the Tropical Rainforest
• It is unfortunate to see how the tropical rainforest
is dying little by little as time goes by.
• Deforestation is ravaging the areas Central and
South America as well as Asia, parts of Africa and
Australia.
• Although tropical forests cover only about a
small percentage of the Earth’s dry land, they
probably harbor about half of all species on Earth.
Many species are so specialized to microhabitats
within the forest that they can only be found in
small areas. Their specialization makes them
vulnerable to endangerment and extinction.
• In addition to the species lost when an area is
totally deforested, the plants and animals in the
fragments of forest that remain also become
increasingly vulnerable, sometimes even
committed, to extinction.

59. Recycle and reuse electronic devices
As our society is becoming more dependent on electronic
devices in their every day lives, an urge to educate our whole
society unto how to recycle dying or non-functioning electronic
material. Often some equipment might be reusable or could be
taken apart to several separate piece to be reused into other
electronic objects.
Companies such as HP are taking action reinforcing their
policies on recycling electronic equipment. Simple actions
towards educating society into this way of thinking is definitely
large steps into making this planet a better place to live.
Here are some small steps you can take to recycle, reduce and
reuse electronic devices:
• Recycle inkjet cartridges
• Some companies offer recycling services directly on
their websites
• Donate your equipment to good will, often this
electronic equipment can be sent to different areas in
the world where computers and other kinds of materials
are needed.
• Shop for items that are energy
friendly and that aim to reduce
energy use.
• Reconsider twice throwing
away your electronic equipment.
Try reusing it.

60. Composting
• Composting is another great solution to reducing the amount of waste.
Government programs are being developed to educate people on how to practice
composting.
• Ground-up food clogs pipes places additional load on the wastewater treatment plants.
• Composting helps reduce greenhouse gas (GHG) emissions by reducing the number of
trips trucks must make to the landfill as well as the amount of methane released by our
landfills.
• Adding compost to lawns and gardens helps them retain moisture, requiring less
watering. Applying compost to your lawn will also protect it, reducing the need for
pesticides, which are harmful to the environment.
