7 RAW MATERIALS &

8 It’s All From Nature EVERYTHING we use comes from, and is returned to nature…

9 NATURE? bauxite ore caustic soda magnesium manganese iron silicon copper

10 NATURE? cotton pesticides chemical dyes petroleum copper, zinc iron, carbon

11 It’s All From Nature EVERYTHING we use comes from, and is returned to nature… …but how much can the Earth handle?

12 So, how much land is there?? Earth 51 billion hectares

13 What is a hectare (ha)? Unit of measurement Commonly used for measuring land 100m x 100m 2.47 acres Approximately one official soccer field

14 Earth 51 billion hectares

15 PARTIAL LAND

16 PRODUCTIVE

17 Let’s Do the Math… 51 billion hectares LAND: 18% of that is productive land How many hectares of productive land? WATER: 5% of that is productive water How many hectares of productive water?

18 Not a whole lot of room! There are over 7 BILLION PEOPLE who live on the Earth That means there’s only 1.7 hectares available for each of us!!

19 Not all footprints are the same… Every lifestyle has a different footprint, and on average, so does every country… Available 1.7 ha Canada 8.8 ha India 0.5 ha United States 10 ha

20 In Canada, our footprint is That means we are using more land than is available to sustain our lifestyles 8.8 hectares per person

21 Canada What if everyone lived as we do?
