I would ask what methods you imply when you say organic farming is only such a small percent less efficient, honestly. Also how less energy is used.
As for composting?
"Oookay... Firstly, pesticide = poison. It's why those things work."
Antibiotics = poison. Many medicines you use = poison. Pesticides are tailored to be poison to a *specific pest*. In fact, many common pests have no 'organic' control as yet, which means that said pests can ruin organic crops much more easily, which lowers productivity and actually makes for *more* waste.
"Secondly, your shit argument is, pardon the pun, complete bullshit. The manure is first composted, which, by the way, kills just about all of the harmful stuff in the faeces."
And no offense, but composting does not do that. You refer to what is called 'de-biological treatment'. And also no offense, calling bullshit and then saying 'just about' isn't very scientific either. Manufactured fertilizers have *no* harmful biologicals, period. That's why professionals use it. They don't take a chance on 'maybe'.
I agree with a more balanced version, but let's be honest here. The 'sides' of this argument don't *want* a balance. They want 'the way it's been done' or 'organic is better', which means there's no real middle ground.
