Final answer:
The appropriate size of an ecological footprint per person in order to live sustainably varies depending on region and available resources. However, a sustainable ecological footprint is considered to be around 1.7 global hectares per person.
Step-by-step explanation:
The appropriate size of an ecological footprint per person in order to live sustainably varies depending on the region and available resources. However, in general, a sustainable ecological footprint is considered to be around 1.7 global hectares per person. This means that an individual's consumption and waste should only use the resources and capacity of 1.7 hectares of land per year. For example, if someone lives in an area with abundant renewable resources, their ecological footprint may be higher than someone in an area with limited resources. On the other hand, individuals in highly developed and industrialized countries often have much larger ecological footprints compared to those in less developed regions. The goal is to reduce overall resource consumption and waste generation to ensure sustainability.
