Its all from nature
EVERYTHING we use comes from, and is returned to nature…
…but how much can
the Earth handle?
Definition: ecological footprint
The amount of productive land
needed to produce all of the things we use and all of the waste
we create
What exactly is an ecological footprint?
It is the IMPRINT we leave on the Earth when we use land for:
- Food - Energy- Waste- Water- Transportation
What is a hectare (ha)?
•Unit of measurement•Commonly used for measuring land•100m x 100m•2.47 acres•Approximately one official soccer field
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?
Not a whole lot of room!
There are over 6 BILLION PEOPLE
who live on the Earth
That means there’s only 1.9 hectares
available for each of us!!
- no car- no water- no electricity- live off the land
- no car- no electricity- markets for food- well for water
- two cars- 45 lights and 3 TVs- heated swimming pool- grocery stores- two plane trips a year- weekly garbage pickup
Every lifestyle has a different footprint
Not all Footprints are the same…Every lifestyle has a different footprint,
and on average, so does every country…

Canada
8.8 ha
