AP ENVIRONMENT CHAP 1 ECOLOGICAL FOOTPRINT
3. Rank of the countries in order from the largest to the smallest per capita ecological footprint
1. United States 2. Canada 3. United Kingdom 4. Germany 5. Japan 6. Russia 7. Mexico 8. World 9. Brazil 10. China 11. India
2. Which two countries have an ecological credit?
Canada and Brazil
China's economy is projected to grow at a rapid rate ,
China will need two-thirds of the world's current grain harvest, twice the world's current paper consumption, and more than all the oil currently produced in the world.
equation I = P × A × T.
Impact (I) = Population (P) × Affluence (A) × Technology (T)
The per capita ecological footprint
It measures the average environmental impact of individuals or populations in different countries and areas
Compare the total and per capita ecological footprints of the United States and China.
The United States has more than six times the per capita ecological footprint of China (U.S.A. 9.8 vs China 1.6). However, the United States' total ecological footprint (2,810 million hectares) is only slightly larger than China's (2,050 million hectares).
1. Which two countries have the largest ecological deficits?
United States and United Kingdom
IPAT model to estimate the impacts of the human populations in less-developed countries
are population size and the degradation of renewable resources as a large number of poor people struggle to stay alive
Why do you think each of these countries has an ecological credit?
because they use less global hectares to sustain their way of life than their own land mass provides.
Why do you think ( US and UK) have such large deficits?
because they use more global hectares to sustain their way of life than their own land mass provides.
Use the ecological footprint concept to explain how we are living unsustainably
global ecological footprint exceeded the earth's biological capacity to support humans and other forms of life indefinitely by at least 30%
Describe the environmental impacts of China's new affluent consumers ( growth of its middle class)
has the world's largest population and second-largest economy. China leads the world in consumption of goods such as televisions, cell phones, and refrigerators The environmental impact of this consumptive growth is the continued polluting of its natural resources
IPAT model to estimate the impacts of the human populations in more-developed countries,
high rates of per capita resource use and the resulting high per capita levels of pollution and resource depletion and degradation
an ecological footprint
is a measure of the average environmental impact of populations in different countries and areas.
What is the IPAT
is a simple model showing how population size (P), affluence, or resource consumption per person (A) and the beneficial and harmful environmental effects of technologies (T) help to determine the environmental impact (I) of human activities.
What is an ecological footprint?
is the amount of biologically productive land and water needed to supply a population with the renewable resources it uses and to absorb or dispose of the wastes from such resource use.
What is a per capita ecological footprint?
is the amount of biologically productive land and water needed to supply each person or population with the renewable resources they use and to absorb or dispose of the wastes from such resource use.
Ecological tipping point
is the point at which an environmental problem reaches a threshold level, which causes an often irreversible shift in the behavior of a natural system.
The IPAT model gives us a mathematical way to track .....
the impact of each country individually or to compare a country's performance.
