Sharing Earth Fairly Wrap-up to Personal Eco-Footprint Calculator

1. How do your results compare with the following average ecological footprints? Average world footprint = 2.7 High Income Countries (average) = 6.1 – Canada = 7.0 – Denmark = 8.3 – New Zealand = 4.9 Middle Income Countries (average) = 2.0 – Vietnam = 1.4 – India = 0.9 – Ecuador = 1.9 Low Income Countries (average) = 1.2 – Haiti = 0.7 – Cambodia = 1.0 – Ethiopia = 1.1 1 ha = 2.4 acres Data as of 2010 All measured in hectares (ha)/person

2. Calculate how much of Earth’s biologically productive land is available to each person on the planet. Divide the total area of biologically productive land (12 billion hectares) by the number of people on the planet (~7.1 billion) 12 billion hectares = ?? Hectares/person 7.1 billion hectares This is known as the “Average Earth Share”

3. Calculate how many Earths would be needed if every human had an ecological footprint the same size as yours. Divide your ecological footprint by the average earth share. Your Eco-Footprint = How many earths needed 1.7 ha How many additional earths would be needed to meet human demands if everyone lived as we do?

Remember! The limited amount of biologically productive land that supports us also needs to provide food, water and shelter for more than 10 million other species. These needs were not factored into the Average Earth Share, which represents the needs of humanity only. Also consider the implications of living in a world where 80% of humans use 20% of the available resources, while 20% (i.e. those of us in wealthier countries) use 80% of the available resources.
