In order to estimate human impact on the environment we can:
A) multiply the number of people times affluence per person times resources needed and wastes produced: I=P x A x T
B) multiply resource depletion times number of years divided by number of people: I = R x Y ÷ P
C) multiply birth rate times consumption patterns divided by available resources: I= B x C ÷ R
D) Divide number of people by resources needed and wastes produced: I = P ÷ T
E) None of these choices; the human impact cannot be measured

The equation I=P x A x T, also known as the IPAT formula, is a commonly used model for estimating the human impact on the environment. It takes into account the population size (P), affluence per person (A), and technology (T) used to obtain resources and dispose of waste. This formula allows for a comprehensive analysis of the impact humans have on the environment and can be useful in identifying areas where interventions may be necessary. Option B only considers resource depletion and time, while option C only considers birth rate, consumption patterns, and available resources. Option D only divides the number of people by resources needed and wastes produced, without taking into account the affluence per person or technology used. Option E is not true, as there are various methods for estimating human impact on the environment.
