Food Production [Biology only]

Food security

• Food security is having enough food to feed a population
• Biological factors threatening it:
  • The increasing birth rate in some countries
  • Changing diets in developed countries, so scarce food is transported around the world
  • New pests and pathogens that affect farming
  • Environmental changes: famine when rains fail
  • The cost of agricultural inputs (fertiliser, fuel, machinery)
  • Conflicts that affect the availability of water or food
• Sustainable methods must be found to feed everyone on Earth
