"The more we come to study the major problems of our time, the more we come to realize they cannot be understood in isolation. They are systematic problems, which means they are interconnected and interdependent."
"environmental concerns have become of paramount importance."
"For example, stabilizing world population will be possible only when poverty is reduced worldwide."
“The magnitude of the effects of human actions on our life-support systems and the goods and services they supply can be visualized as the products of three factors, summarized in the I = PAT identity.”
Ehrlich & Ehrlich, p. 205.
I (impact) is the product of P X A X T
I stands for “impacts” or aggregate effects of humans on the natural capital accumulation of the biosphere in different areas and in different periods.
P is equal to population, especially population density
A is equal to affluence (per capita wealth) or income inequity &
T is equal to technology, or technological capability (electricity-use) or carbon emissions (?)
The I=PAT formula is a short-hand method or way of determining a relative means of measuring the differences in demands between very varied societies of nations, or states, or cities. It is not an accurate measure to the extent that the PQLI or Physical Quality of Life Index is a measure used by international aid organizations for understanding the social, economic and political conditions of a nation or region in relation to its neighbors and other countries.
The ABCs of impacts are:

The impact formula reveals how human behavior affects, alters, or adjusts to nature.
