      - Battery Farming
      - Disease Control
      - The disadvantages of using these methods are:
        
        Excess use of antibiotics in farm animals for disease control could increase bacterial resistance and still be present in meat we eat.
        
        Battery methods show poor animal welfare and the
        duty of care to treat animals humanely.
        
        and more
- - - - The nitrates in the sewage and fertilisers increase the
        growth of algae and water plants.
        
        When these die they are broken down by microbes, the increase in food for the microbes allows them to increase in number
        
        Respiration of the microbes use up the oxygen in the water so fish and other aquatic organisms suffocate and die
- - - - They accumulate along the food chain until they
        reach toxic levels
        
        this causes
        reduced fertility or death in top predators.
