what does carbon footprint mean
What does carbon footprint mean?
  • a measure of the impact our activities have on the environment (climate change)
  • It relates to the amount of greenhouse gases produced in our day-to-day lives through burning:
    • fossil fuels for electricity
    • heating (oil or propane furnaces)
    • transportation
  • Measured in tonnes (or kg) of carbon dioxide equivalent.
  • Developing/supporting renewable energy sources like

wind power can help us reduce our carbon foot print

why does it matter how much carbon i produce
Why does it matter how much carbon I produce?
  • Because there are 7 Billion “I’s” on Earth
    • In October 2011 the world population broke the

7 billion people mark

  • If everyone says someone else will do it, we have 7 million people not helping to solve the problem
  • Businesses alone can not solve this problem, but they do have a role
why does carbon dioxide matter
Why does carbon dioxide matter?
  • It is a green house gas
    • This means that it helps to trap solar radiation in the Earth’s atmosphere
  • Most scientists agree that the world’s temperature is going up
  • Most scientists agree that the increase in temperature is melting ice caps—causing sea levels to increase
so why do i care about polar bears
So? Why do I care about polar bears?
  • They are cute
  • We shouldn’t just kill them because we can
  • Because melting ice becomes water…
melting ice becomes water
Melting ice becomes water?
  • So you don’t care about polar bears
    • You don’t think they are cute
    • You could care less if they become extinct
    • You think Coca – Cola will find a new mascot
  • Then be selfish—if water levels rise because of the melting arctic ice fields…
rising ocean level predictions
Rising Ocean Level Predictions
  • Some predictions estimate that if all of the sea ice melts ocean levels could increase by 61 m
  • There is very little agreement about the rate of sea level rise, but there is agreement it is happening
  • Many predictions suggest a 1 m increase in the next 100 years
if sea level rises about 1m in halifax
If sea level rises about 1m in Halifax:

- the blue area will be water

- the yellow area is where storm surge will stop

what does that really mean
What does that really mean?
  • Over 600 million people live in coastal areas that are less than 10 meters above sea level
  • Two-thirds of the world’s cities that have populations over five million are located in these at-risk areas
  • Underwater cities could become a reality
rising global temperatures
Rising Global Temperatures
  • Scientists do not agree on the rate of temperature increase, but most do agree an increase is happening
  • IF global temperatures rise we could experience:
  • Stronger weather systems (Ex. Hurricanes)
  • More heat waves
  • Changes in seasonal weather patterns that could cause droughts—crop failure

the information doesn t all agree yet so we could wait to act

The information doesn’t all agree yet, so we could wait to act…

The issue is:

What if we wait too long?

There is a certainty in reducing

our carbon footprint:

It can’t hurt.

what do you think we should do
What do you think we should do?

Task:

Write a 1 page journal response that address:

1. What we should do to reduce our carbon footprint

  • What are 5 things the average person could do
  • Do you think individuals should bother?

2. If you think sea level rise is something we should worry about and why/why not

3. If you think temperature rise is something we should worry about why/why not

how you will be marked
How you will be marked

Main Goal:

I want to see that you thought about it.

85-100: Answer all questions and give excellent detail.

70-85: Answer 2/3 of questions and give good detail.

60-70: Answer 2/3 of questions with some detail.

50-60: Minimum ½ page response that makes sense in relation to the topic questions.
