6
What would be included in your ecological footprint?
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?
