Theories

• Malthus Theory (Pessimistic)


  population growth will always increase at a faster rate than food supply and therefore lead to famine and starvation
• Boserup Theory (optimistic)


  when population growth begins to approach limits of food production, people are motivated to invest in new technology and better farming techniques
• Malthus Theory - detail


  population explosion leads to 'point of crisis'

  'point of crisis' = famine, poverty, civil war, crime etc
• Boserup theory - detail

  'necessity is the mother of growing inventions'

  e.g. vertical farming in underground stations and hydroponics which is an efficient way to water crops
