  • INTENSIVE FARMING
    • Used to produce more food
      • Method 1: using herbicides to kill weeds
        • This kills unwanted plants which stops wasting energy from the sun and focuses the energy on water crop growth
          • Increase Crop Yield
      • Method 2: using pesticides
        • This kills insects that eat the crops which stops energy being transferred to another food chain and focuses the energy on the crop
          • Increase Crop Yield
      • Method 3: battery farming animals
        • This is when the animals are kept close together indoors so they are warm, safe and don't move around as much so the energy is not wasted and focused on animal growth
          • Increase Amount of Food Produced
      • Method 4: Hydroponics
        • It is when you grow plants in a solution rather than in soil
          • Example: Glasshouse Tomato growth on a commercial scale
          • Advantages; mineral levels and disease can be controlled
          • Disadvantages: fertilisers are needed and there is no anchor or support for the the plant
    • TRYING TO PRODUCE AS MUCH FOOD AS POSSIBLE FROM A RESOURCE
    • Enables farmers to produce a lot of food from a small amount of land
      • Causes a huge variety of top quality food to be available, all year round at low prices
      • BUT IT CAN DESTROY THE LAND AND THERE ARE ETHICAL DILEMMAS
        • They can make the environment look unattractive and devoid of wildlife and can pollute it
        • Main Effects
          • Removal of hedges destroy habitats and soil erosion
          • Fertilisers can pollute rivers and lakes (eutrophication)
            • Pesticides can also damage food chains
          • Intensive Farming of animals is seen to be cruel due to the horrible conditions
            • An example are battery-hens
