Population Perspectives
- Malthusian (and neo-malthusian) perspectives
- negative population perspectives, population can't be sustained and will decline as result of insufficient resources.
- MALTHUS (1798): Pop increases exponentially , resources increase linearly =pop run out of food and resources, and pop decrease. pop will decrease due to number of positive and preventative checks when population becomes too high.
- Positive check: disease, war, famine - disaster that significantly reduces pop.
- Preventative check: cultural choice to lower pop, e.g choosing not to have children as you will not be able to support them.
- negative population perspectives, population can't be sustained and will decline as result of insufficient resources.

- Non-malthusian perspectives
- positive population perspectives, stating pop can be sustained and will find new ways to support the population.
- Boserup :no matter how large pop grows, the pop will always discover new ways to sustain food supplies , e.g. technologies and systems.
- Simon : humans are ‘the ultimate resource’ , and in spite of finite resources, humans will come up with new ways to sustain resources (e.g. finding new materials, recycling, new means of energy).
- positive population perspectives, stating pop can be sustained and will find new ways to support the population.
