"A group of high profile New Zealanders talk about climate change and why they Signed On at http://www.signon.org.nz to ask NZ Prime Minister John Key to go to Copenhagen to Sign NZ On to 40 per cent emissions reduction by 2020."
It's so necessary.
Population control has to be part of it.
Clean energy has to be part of it.
Personal sacrifice must be part of it.
But 40% still seems like so very much.
How can we do it, really?
"Sign on" -- Okay. Now what?
