COURSE SUMMARY FOR GLOBAL WARMING COURSE FALL 2019...

Description



The IPAT model represents how our total impact (I) on the environment results from the interaction of population (P), affluence (A), and technology (T).

I=P×A×T





Increased population means more individuals take up space, use resources, and generate waste.



Affluence leads to greater per capita resource consumption.



Technology can increase impact by enhancing our ability to exploit resources or decrease impact by improving efficiency.

A sensitivity factor (S) may also be added to denote the vulnerability of a given environment.

I=P×A×T×S  



For example, the arid lands of western China are more sensitive to human disturbance due to the slow growth rate of the plants there.

Modern-day China has many examples of how IPAT elements can create environmental impact. 

Intensive agriculture has caused erosion in western China similar to the Dust Bowl.



Aquifers and rivers are heavily withdrawn.



Air quality is so low in Beijing, that breathing it for a day is similar to smoking 40 cigarettes.

As shown by this graph, the human population is experiencing _____ growth. 

linear



exponential



logistic

negative 1. As shown by this graph, the human population is experiencing _____ growth. a. linear b. exponential c. logistic d. negative 2. According to the IPATS model, which of these changes would reduce environmental impact? a. An increase in the overall affluence of the global society b. An decrease in the human population growth rate

c. Technological advances in resource harvesting d. Consuming resources in a more sensitive environment 3. According to the IPATS model, which of these changes would reduce environmental impact? a. An increase in the overall affluence of the global society b. An decrease in the human population growth rate c. Technological advances in resource harvesting d. Consuming resources in a more sensitive environment 4. Study of human population 5. Application- applies principles of population ecology can be applied to the study of statistical changes in the human population. 6. Despite our ability to use technology to keep up with our population growth, our knowledge of population ecology and logistic growth suggests that this cannot continue indefinitely....
