While we are looking at electrical things ; someone, on hypography, was looking into whether low-energy lamps were net savers of CO2.
Does anyone know if the production of the lamps costs more in CO2 than they save?
My local electricity authority is giving away six for free. (Unfortunately most of my light fittings are recessed and I don't think you can use them in recessed fittings.).

How much power do you save by not leaving TVs on stand by mode?
Thanks for the tip re iron and phytoplankton. That is a pretty impressive experiment. Why Iron? What does it do? Half of western Australia is made of iron. We could easily chip a few bits off into the sea.
I will go and read the links you gave now.
I don't think DDT ever breaks up into much; DDE perhaps, which is just as bad.
It just spreads out. "Witholding periods" are the time it takes to spread out off your tomatoes so you don't get too letal a dose, not the time it takes to break down. (The half life for most CHs is 18 years -we think.) If it was biodegradable I wouldn't object to it as much.
I have a couple of research papers on this if you are interested although most of my knowledge of this deleterious effect of Chlorinated Hydrocarbons on plankton comes from concerned and informed chemists. You would think that "Round-Up" would be worse than pesticide designed to kill bugs not "Grass -with-Attitude"
