7.2c Flashcards
Internationally, how much more natural resource material do we extract than 30 years agp?
50% more
For food, water, energy etc
What does the biosphere provide us with?
Clothing, energy, food, buildings
How much more do developed countries consume as opposed to developing countries?
10 fold due to rising affluence increasing demand
What is a reason for global demand and consumption/
Increasing population and wealth
What are the regional trends in Asia?
High population growth and development rate compared to Europe
Leads to increase in wealth
Wealth, urbanisation, industrialisation has led to more resource consumption and demand
- People get richer, more expensive diets (e.g. meat and dairy)
What has urbanisation and industrialisation led to?
Increased demand for resources for factories, and increased demand for resources to invest in infrastructure and city structure.
Give examples of exploitation which have affected the biosphere.
- Demand for beef, led to deforestation
- Demand for palm oil, deforestation
- HEP building has led to flooding behind the dams.
- Boreal forest destroyed through open-cast mining.
Summarise Malthus’s theory.
- Human population is geometric
Human population growing faster than food production - Epidemics would occur when there isn’t enough food
- War would kill people reducing the population to counter the issue of lack of resources.
- Famine and disease would also kill.
Give an argument against Malthus’s theory.
New ways of food and resource production has been found
E.g. Green Revolution - high yield crop
As countries develop birth rates drop
Summarise Boserup’s theory.
Although the population is increasing, human ingenuity would find new technologies and methods of food and resource production as we develop further to keep up with demand.
E.g. selective breeding, irrigation, pesticides.
