1. Technology is Destroying
our Planet
The Automobile and
Global Warming
By Brody Johnston

2. The Automobile
The Automobile is the most
revolutionary piece of technology to
emerge from the field of transportation.
The impact cars have had on our society
is tremendous. Allowing people to travel
long distances in a very short amount of
time. It is estimated that there are
about 600 million vehicles in the world.
From this it is obvious that the
automobile has impacted our society in a
serious way; not just economically, or
socially, but also environmentally.

3. Pros of the Automobile
 Technology that revolutionized the way
we trade, transport people and goods.
 The ability to travel where and when
you want at a moments notice.
 Faster response time in emergencies
(ambulance, police, fire trucks, etc.).
 Faster, more localized transportation
of goods and services.
 Overall societal
Independence

4. Cons of the Automobile
 Cars are expensive, (insurance, gas,
maintenance fees, etc.).
 Can be deadly. Collisions in cars is
the #1 cause of teenage deaths.
 Causing our society too be unhealthy
and lazy due to lack of exercise.
 The increase in car users is causing a
lot of congestion on the roads.
 Negative Impact on the
environment:Cars exhaust fumes
are causing global warming.

5. What is Global Warming?
Global warming is defined as,
“The progressive gradual rise of
the earth's surface temperature
thought to be caused by the
greenhouse effect and
responsible for changes
in global climate
patterns” (Natsource).

6. The Effects of Global Warming
 Why is Global Warming such a big deal?
 Global warming is having a huge impact on
our planets climate today.
 The increase of the Earths temperature, is
slowly causing a variety of problems.
 Floods, and bigger and
stronger storms are some
of the smaller immediate
issues.
 Global warming however, has
the power to destroy our planet.

7. The Increase in
3 Main Greenhouse Gas
Emissions
Causes
of Global
Warming
Global
Deforestation
The
Depletion of
the Ozone
Layer

8. Cars and Greenhouse Gases
 The majority of cars on Earth burn
fossil fuels. (Gasoline, Diesel, oil,
etc.).
 The combustion of theses fossil fuels
releases pollutants into the atmosphere.
 These pollutants are known as
Greenhouse gases, released from the cars
muffler.

9. Greenhouse Gases
 Greenhouse gases are the number one
cause for global warming.
 Released into the atmosphere primarily
through the Combustion of fossil fuels
in cars, factories, and electricity
production.
 Greenhouse gases are made up of CO2,
nitrous oxide, and methane (All
released from automobiles exhaust).
 CO2 causes a greater temperature
increase than any other gas.

10. Trees and Carbon Dioxide
 Animals produce
CO2, and plants
produce oxygen.
 Natural Harmony
 Deforestation
Disrupts this process.
 Trees store CO2, they are a
naturally occurring defence against
the buildup of CO2 in our atmosphere
from pollutants such as car exhaust.

11. Deforestation
 As we continue to become a more
technologically advanced society, the
amount of industry increases.
 More Cars = More Carbon Dioxide
 With more industry we are also seeing
more deforestation.
 Less Trees = more
Carbon Dioxide
 More CO2 = More
damage to ozone
layer

12. Ozone Depletion
 Ozone Depletion is the number one cause
for the increase in temperatures world
wide.
 Ozone Depletion is caused from the
release of greenhouse gases.
 Holes in the ozone layer allow UV rays
into our atmosphere.
 CO2 build up in our atmosphere traps
heat(The suns UV rays)at the surface.
 Hotter surface temperatures = colder
temperatures in the ozone layer.
 The colder the temperature in the ozone
layer, the harder it is for the ozone to
naturally replenish.

14. Evidence of Ozone Depletion
 By the year 2000, 60% of the ozone
layer covering the Arctic region
was lost.
 Currently over the Antarctic the
ozone hole is three times the size
of the United States.
 This is why the
Arctic regions are
showing the greatest
temp increases.

15. The Automobiles Impact on Climate
 The automobile was invented in the
early 1900’s. During the Industrial
Revolution.
 The Industrial Revolution caused a
higher % of greenhouse gas emissions.
 This pollution results in higher
global temperatures.
 The global temperature
average has risen 0.7
degrees Celsius since
the 1900’s.

16. Evidence of Climate Change
 In 2006 24% of the ice in the polar
arctic region disappeared.
 It was this same year that the
Northwest Passage was free of ice for
the first time in recorder history.

17. Effects of Global Warming
 The Arctic Regions
house 96% of the glacier
ice on Earth.
 If it melted, sea
levels would rise up to
25ft world wide.
 The damages this
would cause would be
incomprehensible
 If not taken
seriously global
warming will destroy
our planet.

19. How to Beat Global Warming
 To improve our chances
of stopping global
warming there are a few
things we as a society
can do…
 Drive less/walk more = fewer emissions.
 Get your car E-Tested or consider
buying an electric car.
 Reduce, Re-use, Recycle.
 Cut down on electricity
 Use less heat/air conditioning
 Buy more energy efficient products
