This is certainly true, however, good can come from bad.  Invest in organic seeds, and start a vegetable garden.  You will not only have 'free' vegetables [after you have collected your own seeds] but you will have enough to sell to your neighbours.  They'd just love the taste and nutrition from home grown vegetables, picked daily. 

If you don't have enough space to grow vegetables [even a balcony using polystyrene boxes] there are plenty of community gardends starting up.  Again, buy the organic seeds and sell the produce.

Another idea is to visit an Aged Care village, offer to grow vegetables in their garden and sell them back to their kitchen....keeping some for yourself.  You'll soon be keeping diabetes & high blood pressure  at bay, as well as having a small income.  If you can work every day in 5 different gardens, you will have more than a small income.
