Final answer:
Ehrlich's I=PAT formula is used in sustainability analysis to understand the impact of human activities on the environment. It represents the idea that environmental Impact (I) is the product of Population (P), Affluence (A), and Technology (T). By analyzing the variables in the formula, we can identify factors that contribute to unsustainable practices and work towards more sustainable solutions.
Step-by-step explanation:
Ehrlich's I=PAT formula is used in sustainability analysis to understand the impact of human activities on the environment. The formula represents the idea that environmental Impact (I) is the product of Population (P), Affluence (A), and Technology (T). Population refers to the number of individuals using resources, Affluence represents the consumption patterns and lifestyle choices of individuals, and Technology represents the efficiency and environmental impact of the technologies used. By analyzing the variables in the formula, we can identify factors that contribute to unsustainable practices and work towards more sustainable solutions.
