The ecological footprint is a measure of how much land and water area a person or population requires to produce the resources they consume and to absorb the waste they generate, expressed in global hectares (gha). If it is stated that someone lives in a way that requires 5.6 Earths, this means that their ecological footprint is significantly larger than the planet's capacity to regenerate resources and absorb waste.
To understand what that translates to in terms of ecological footprint:
1. **Global Biocapacity**: Earth has a biocapacity of roughly 1.8 global hectares per person per year (this is an approximation; it varies based on different sources and ecological assessments).
2. **Calculating Footprint**: Since 5.6 Earths would imply that their ecological footprint is 5.6 times the global biocapacity, you can calculate the footprint in global hectares:
\[
\text{Ecological Footprint} = 5.6 \times \text{Biocapacity Per Person}
\]
3. **If we assume a global average biocapacity of about 1.7 global hectares per person, then**:
\[
\text{Ecological Footprint} \approx 5.6 \times 1.7 \approx 9.52 \, \text{gha}
\]
So, if someone has an ecological footprint that requires 5.6 Earths, their ecological footprint would be approximately 9.5 global hectares per year. This number illustrates a lifestyle that is extremely resource-intensive and unsustainable on a planetary scale.
