Ecological footprint measures our use and demand of nature and how much nature we have. It measures how much quantity of nature can be used to support people or an economy and it tracks this demand through an ecological accounting system.
Ecological surplus or deficit measures what is left over or how little a country's biocapacity is available. It is calculated by subtracting the country's ecological footprint per person from the country's biocapacity per person. They are both measured in global hectares (gha)

The first comprehensive lifespan view was developed by Erik Erikson. It is called the Erikson's stages of psychosocial development which identifies eight stages where a developing individual should be able to go through from infancy to adulthood. These stages are infancy (0 to 23 months), early childhood (2 to 4 years), preschool years (4 to 5 years), school age (5 to 12 years), adolescence (13 to 19 years), early adulthood (20 to 39 years), adulthood (40 to 64 years) and maturity (65 to death). In each stage, specific values, psychosocial crisis, significant relationship and existential question are being specified by Erikson.
