1 HOW BIG IS YOUR FOOTPRINT? LEARNING ABOUT HOW WHAT WE DO CHANGES THE PLANET

2 Think About This… You are on a school trip on a hike. You are asked to walk through the forest without hurting anything. You are on a school trip on a hike. You are asked to walk through the forest without hurting anything. You get to the other side, and say Sir! I did it! You get to the other side, and say Sir! I did it! Then you think about it…you have stepped on plants and killed them, you have pressed down the dirt so things cant grow, you scared animals (wildlife) and you have crushed flowers so they cannot grow. Then you think about it…you have stepped on plants and killed them, you have pressed down the dirt so things cant grow, you scared animals (wildlife) and you have crushed flowers so they cannot grow. Your hike HURT the environment, even though you didnt mean to. Your hike HURT the environment, even though you didnt mean to.

3 But Im Not a Bad Person, Right? OF COURSE NOT! The idea isnt to make you feel bad, it is to help you understand how every little thing you do can affect the planet. The idea isnt to make you feel bad, it is to help you understand how every little thing you do can affect the planet. So now we see…everything we do can hurt the planet, so… So now we see…everything we do can hurt the planet, so… WE HAVE TO BE CAREFUL! WE HAVE TO BE CAREFUL!

4 Your Footprint What size shoe do you wear? What size shoe do you wear? When you walk your shoe leaves a FOOTPRINT in the dirt, snow or sand. When you walk your shoe leaves a FOOTPRINT in the dirt, snow or sand. If you have a bigger shoe, you have a bigger footprint, right? If you have a bigger shoe, you have a bigger footprint, right? Well, its like that with the environment…some countries hurt the planet A LOT, other dont hurt it very much. Well, its like that with the environment…some countries hurt the planet A LOT, other dont hurt it very much.

5 Your Ecological Footprint Your ECOLOGICAL FOOTPRINT is a way of talking about HOW HUMANS HURT OR CHANGE THE PLANET. Your ECOLOGICAL FOOTPRINT is a way of talking about HOW HUMANS HURT OR CHANGE THE PLANET. If you have a big ecological footprint, you use LOTS OF THE EARTHS RESOURCES If you have a big ecological footprint, you use LOTS OF THE EARTHS RESOURCES If you have a small footprint, you do use FEW OF THE EARTHS RESOURCES If you have a small footprint, you do use FEW OF THE EARTHS RESOURCES

6 How do we Talk About Ecological Footprint When we talk about ECOLOGICAL FOOTPRINT, we are really talking about how much land is needed to make all the energy and resources EACH PERSON USES When we talk about ECOLOGICAL FOOTPRINT, we are really talking about how much land is needed to make all the energy and resources EACH PERSON USES Ecological Footprint also includes ALL the land needed to deal with the waste (garbage and pollution) EACH person makes Ecological Footprint also includes ALL the land needed to deal with the waste (garbage and pollution) EACH person makes

7 Measuring Your Footprint If you go to a shoe store, you measure your footprint in a machine like this… If you go to a shoe store, you measure your footprint in a machine like this… If we are talking about your ecological footprint, we are talking about how many HECTARES of land (worth of resources) each person uses If we are talking about your ecological footprint, we are talking about how many HECTARES of land (worth of resources) each person uses

8 How Big is That? ONE HECTARE is an easier way of saying square meters… ONE HECTARE is an easier way of saying square meters… In other words, ONE HECTARE IS roughly times the size of your desk. In other words, ONE HECTARE IS roughly times the size of your desk. The average Ecological Footprint for the whole world is 2.8 ha (hectares) per person. The average Ecological Footprint for the whole world is 2.8 ha (hectares) per person. Canadians use 7.7 hectares per person. Canadians use 7.7 hectares per person. Therefore, Canadians have a much bigger Ecological Footprint than most people in the world. Therefore, Canadians have a much bigger Ecological Footprint than most people in the world.

9 We Cant be THAT Bad… Oh yes, we can! Here is a graph that shows the countries of the world, and how big their footprint is. Canada is the 4 th worst! Oh yes, we can! Here is a graph that shows the countries of the world, and how big their footprint is. Canada is the 4 th worst!

10 Individual Footprint The following are things we each do that affect how big our ecological footprint is… The following are things we each do that affect how big our ecological footprint is… 1. Amount of food and type of foods we eat 2. Amount of and type of electricity we use 3. Size of your house of appartment 4. Amount of things you buy 5. How efficient (environmentally friendly) your house or car is 6. How far you have to go to get to where you are going, and how you get there (bus, bike, car, walk)

11 City,Town or Regional Footprint Here are some factors that affect how big a regions footprint is… Here are some factors that affect how big a regions footprint is… 1. Population Density (ppl per square km) 2. How many people live in a house 3. How much money each of us spends 4. How much energy the area uses 5. How their land is used

12 What Kind of Things have a HEAVY FOOTPRINT? These things make your footprint REALLY BIG… These things make your footprint REALLY BIG… 1. Sport Utility Vehicles and Big Trucks 2. Big Highways 3. Polluting Power Plants (Coal) 4. Going to work or school in a car 5. Driving when you could walk or bike

13 Things that have a Light Footprint Biking, Skateboarding or Walking to get places Biking, Skateboarding or Walking to get places Gravel roads Gravel roads Solar power or wind power (they dont pollute at all!) Solar power or wind power (they dont pollute at all!) Public Transit (oc transpo) Public Transit (oc transpo) Walking to school Walking to school

14 Interpreting Cartoons You are going to have to do this on your summative, so lets practice! Flip to page 166 in your textbook Lets check this cartoon out together!

15 Get to It! Read up to page 168 together Read up to page 168 together Answer questions up to page 169 in green boxes for chapter 16 on your own! Answer questions up to page 169 in green boxes for chapter 16 on your own! They are due tomorrow! They are due tomorrow!
