Scale and Context

Sustainability research and a lot of time and space scales on the environmental and social and economic contexts of a number of familiar. economic sectors, the sustainability of the planet Earth for the balance of power with the focus changes, ecosystems, states, municipalities, neighborhoods, home gardens, live in separate, individual goods and services, professions, lifestyles, behavior patterns, and so on. . In other words, it is full, or its biological and human activity on the part of the reason might be Compass Daniel Botkin, author and environmentalist, as stated: "We are changing on the scale that the flux of time and space is always a view to see ". 

Consumer - people, technology, resources 

Biophysical effects of the drive system of human resources, destruction of Earth, and in particular, are ecosystems of Earth. a community of humanity as a whole, or to the environment, and the scale of human impact on per capita, which in its turn, these resources are restored, or, what resources are used depends on the activity of the complex depends on the carrying capacity of ecosystems than take part. Careful resource management organizations, business, agriculture, manufacturing and industrial sectors, such as over-weight can be applied to the economic, physical and personal and household patterns of consumption of goods and services resource requirements. One of the first attempts in 1970 and developed the mathematical expression of human impact on the first formula is known as PAT. Preparation of the three components of the consumer in terms of human attempts to explain this: the number of the population, the level of consumption a unit of impact and resource of technology used depends on the . Expressed in the equation is: I = P × A × T Where: 

I = environmental impact, P = Population, A = affluence, T = Technology
