Population and the
environment revision
,Key Terms
Population density = average number
of people living in a certain area
Population distribution = Natural change – more people
pattern of where people live being born than dying (or vice
versa)
Migration change – people
moving in or out impacts
population
,Industrial Revolution = surge in
populations
Trends now
- Asia = 60% of world’s pop
- Pop is increasing but rate of
change varies eg. Sub-Saharan
Africa is projected to double by
2050 while other areas of
Africa are slowing in their
increase
- Some areas are already
experiencing decline
, Human capacity aka how many
Environmental capacity aka how people are eating that stud and
Food Production
much stuff you can grow what fancy tech they can use to
make more
We are making more food through
- Green Revolution – new tech, new higher yielding varieties
of crops etc
- Increase in global trade which addresses seasonality
- Investment in production LICs by TNCS to increase
productivity
LICs have growing production and consumption bc growing
pops and low starting point of production (+ increasing wealth)
Vs HICs where pop isn’t growing anywhere near as fast so
consumption is levelling out
