Which segues nicely into another "green theme" that of the irrepressible 
light bulb.  Since we have all been encouraged to get rid of our old 
tradition "edison" incandescent light bulbs and replace them with the new 
fluorescent version, there has been very little interest in the mercury that 
these things carry around.   Peter Garrett mumbled something last year but it 
never went very far.

We have decided to not bin them any more, but to collect them in a box in the garage 
until we have 100's of them and then I will call the council to tell them we 
have a load of toxic waste to be properly disposed of.....
