There are so many compelling reasons for growing even a little of your own food in the garden or allotment, on the patio, or even on the windowsill.
Take for instance the humble lettuce. On average of over 11 pesticides are sprayed on lettuces, more than any other vegetable crop. In one study by what is now the UK Department of the Environment, Food & Rural Affairs (DEFRA), pesticide applications had increased by 600% over a ten year period. Those innocent bags of mixed salad from the supermarket are also washed with chloride to prevent decay.
