- Describe the ways that technology can increase food production. How acceptable/ sustainable?
- Hydroponics
- Large quantities produced
- Hydroponics
- Fertilisers, pesticides, herbicides

- Hydroponics
- Increase yields
- Decrease hunger/malnourishment
- Genetic resistance

- Decrease biodiversity
- Fertilisers, pesticides, herbicides
- Increase yields
- Decrease hunger/malnourishment
- Genetic resistance
- Increase yields
- Fertilisers, pesticides, herbicides
- Adverse health effects
- 1-5 million have acute poisoning and die/year
- Herbicide tollerance
- Biotechnology- GM crops
- Developmental process v. expensive
- Biotechnology- GM crops
- Insect tollerance
- Virus tollerance
- Delaying ripening (preservation)
- Biotechnology- GM crops
- Developmental process v. expensive
- Biotechnology- GM crops
- Increasing yields
- Virus tollerance
- Genetic uniformity increases vulnerability to disease
- Decreased biodiversity
- 750,000 pepper picked a week at Thanet Earth/week
- High initial cost
- Drought tolerant
- Reduced use of pesticide
- Grown in water so in areas of poor soil quality or little space crops can be produced
- Hydroponic crops can be grown in stacks above each other
- HIgh energy output
- Mechanisation of farming
- Increase productivity
- Pollution
- Encourages large scale production
- irradiated the need for jobs
- Mechanisation of farming
- Increase productivity
- Pollution
- Encourages large scale production
- Mechanisation of farming
- Deforestation
- Soil erosion
- Improves quality of farm produce
- Technology may be a but advance and too expensive for LEDCs perhaps more suited to NICs / BRIC countries
- Suitable but would have to be careful thats the poorest in society are not cut off
- Suitable but tighter regulations/education on handling the chemicals
- would have to be set to avoid deaths
