While the I = PAT equation quickly became established as the norm and has been used and cited by many organisations and individual people ever since, recently, various alternative formulations of the equation have been proposed. 3. Ehrlich, P.R. Supporting users have an ad free experience! Growing consumption can cause major environmental damage. 2. A plentiful supply of material goods; wealth. Growth in Population and Affluence have exceeded improvements in Technology. For some observers, "consumption" is at the root of global environmental threats: wealthy individuals and societies use far too much of the earth's resource base and should scale back their appetites to preserve the environment for future generations and allow a decent life for the rest of the world.

Situation in which a change in a certain direction provides information that causes a system to change less in that direction. The systematic study of our environment and our place in it. GDP per capita has been growing steadily over the last few centuries and according to the formula I = PAT, called the impact equation, is driving up human impacts on the environment.

The expression equates human impact on the environment to a function of three factors: population (P), affluence (A) and technology (T). Growing consumption can cause major environmental damage. Because of this, their environmental impact is multiplied. According to the Journal of Environmental Psychology, the field can be defined as: “[T]he scientific study of the transactions and interrelationships between people and their physical surroundings (including built and natural environments, the use and abuse of nature and natural resources, and sustainability-related behavior).” For example, the complex processes by which innovation translates into growing industrial productivity also can lead to the disruption or destruction of labor markets and social networks.

Failure to include environmental costs. remain diverse and produce everything it needs for the ecology to remain in balance The equation maintains that impacts on ecosystems (I) are the product of the population size (P), affluence (A), and technology (T) of the human population in question. All socio-economic systems for which the I = PAT question may be posed are embedded not only in natural environments but also in networks of social systems with which they interact. Environment science is the study of earth, air, water living organisms and the man with is impact on environment.

The definition of poverty is being unable to meet one’s basic needs. Poverty impacts the environment negatively. Fischer-Kowalski and Amann (2001) argue that the full understanding of the impact equation must take into account the variety of socio-economic systems in different countries and the effects of globalisation and trade.

(2001) ‘Beyond IPAT and Kuznets curves: globalisation as a vital factor in analysing the environmental impact of socio-economic metabolism’, Population and Environment, 23(1): 7–47. If anything, because of the relatively consistent empirical finding of a negative relationship between country-level affluence and concern over local environmental problems (Brechin 1999; Dunlap and Mertig 1995), global environmentalism scholars might expect to find a negative relationship for general concern and affluence.
