Unformatted text preview: s in the global ecological footprint relative to
global biocapacity over time. Adoption of sustainable practices end ecological overshoot by the year
~2050; Further decreases in EF allow accumulation of biocapacity reserve, which eventually offsets
accumulated ecological debt. Adapted from Hails et al. (2008). Remember that the EF represents the land area required to maintain the current quality of life.
However, it is hard to remember land areas in acres, so the EF is often divided by the biocapacity in acres to
obtain a unitless number. When this is done using the global average biocapacity, the resulting EF is expressed
as the number of earths required to maintain the current standard of living.
To recap, sustainability preserves and grows economic, social, and environmental capital so that
current and future generations can meet their needs and maintain a high level of well-being. It can also prepare
us for the coming challenges posed by Peak Oil and Global Climate Change. References
