- Genetic Manipulation
- Population Control
- Increasing pop^ density = higher productivity. (May lead to quicker spread of disease and increased competition)
- Optimun livestock stocking density different for different species eg. highland and lowland sheep.
- Monocultures
- Growth of a single crop over a large area
- Easy management eg same pesticides - but disease spreads easily.
- Low labour inputs - and so energy inputs
- Large scale and so cost effective using large machinary
- Large fossil fuel inputs because of reliance on mechanization.
- Vegetative Propagation - Asexual
- Cuttings
- End of stem in damp soil, plant hormones help roots grow. Genetically identical plants.
- Micropropagation
- Plant tissue on agar jelly under controlled conditions. Thousands of genetically identical plants.
- Cuttings
- Population Control
