ORGANIC FARMING
Organic farmers do not use the same methods as intensive farmers.
They try to produce smaller amounts of healthy good quality food.
Their approach does not make great use of artificial chemicals

ADVANTAGES
They is no need for artificial chemicals to be used

DEALING WITH PESTS
They use a technique called biological control
They introduce a natural predator for the pest, which will kill the pest
Organic farmers don't use pesticides like an intensive farmer does
This is a much better way
