week 4 and 5 Flashcards
Formula for Impact
Population X affluence x technology
Population: is the amount of people who consume
Affluence: usually expressed by GDP= average economic activity per person
Technology: how resource intensive the production of affluence is
Explain exponential growth
This is when there is a large amount of births, giving it a feedback loop where larger populations lead to more births
Resource environmental management
Is the management of the interaction and impact of human society
Why has the ecosphere been transformed by human actions?
Because people industrialized and altered systems through pollution
Hunter gather society
Small groups people and used fire to modify landscapes
What is doubling time?
Is an estimate of how long it will take for population to double
70/growth rate
Anthropocene
Where human impact is a dominant force, mainly through the industrialization and environmental modification
Agrarian soceity
Domestication of animals and led of surplus production and introduced urban centres
Demographic transition model
Death and birth rate changes as a country develops
Carrying capactiy
The maximum population size the environment can sustain
The carrying capacity goes down because the amount of food, homes, water and other necessity goes down
Paul Ehrilich
In order to drop carrying capacity he proposed to have tax penalties on having kids
DID not become reality
Environmental Kuznets Curve
The solution to pollution is economic growth
As the basic needs of people are covered, pollution declines, but GDP continues to grow
Techno-pressimist
There are limits to growth
Future is uncertain
Our way of life is damaging and can cause a population collapse
