Participating in democracy

Democracy ensures that there are levers waiting to be pushed, but we have to get off our backsides and do the pushing ourselves. In this post I’m soliciting suggestions about where we can find the most useful levers. (Overseas readers are encouraged to contribute – how things work in your neck of the woods might suggest something useful about ours.)
In an earlier post on the ominous climate change policy signals out of the new government, Karen commented: Can we submit something? Start a petition? Idiot/ Morgue?
idiot replied: I expect the inquiry will be open to public submissions, and it might be worth drafting one. That’s good – but I want to take these ideas a bit further.
What can be done to steer John Key and his National government away from the harmful climate change denial of their ACT partners?
* start a petition and submit it to the new government
* make a submission to the inquiry, when it happens
* write a letter to Prime Minister-elect John Key or to other National MPs
? write a letter to the newspaper (:P)
? call your local MP and express your concern
? write a letter to a Ministry (which one?)
I am a total believer in the value of letters from members of the public.
Which are the best ideas in here in terms of delivering change? What am I missing?
In particular, it is worth noting that there is a very clear business incentive to pursue the Emissions Trading Scheme, as pointed out by Gareth at Hot Topic:
“The uncertainty created by the shelving of the current emissions trading scheme legislation is already having a significant impact on the New Zealand economy,” he writes, then details several examples. This should give us even more levers to push. We know that business leaders have the ear of National and ACT – can we put pressure on them with letters, for instance? Who would be worth writing to?
