we don’t really get fruit fly here very much luckily.
there is a book called ‘One Straw Revolution’ written by a Japanese man who inherited his fathers citrus orchard, and through a process of trial and error converted it to an organic farm. One of the main points he made in the book was about how modern technology and practices often solve a problem, but in doing so they create new problems. One has to solve them: and in doing so yet more problems are created. In the end- you are doing more work, for less results than when you started. Australians could learn a LOT from that book.
The problem in a case like this- is that when a person sprays pesticides- they create new problems- but they cannot see them- and maybe they do not have to deal with them. So they don’t even realise what they have done. Or they don’t care. Basically the can is just kicked down the road. Well- now all the chickens are starting to come home to roost as we can only turn a blind eye to the affects of our actions for so long. Unfortunately we seem to be slow on the uptake, and by the time we realise the full scope of the problems it may be too late to do anything about them.
