Our best bet to combat Climate change from New Zealand is to come up with better technologies we can provide to much bigger nations to help them reduce their Carbon/waste output
We're 21st in the world for per capita greenhouse gas emissions. We punch FAR above our weight.
We can't say we are too small and don't matter because every person on Earth can say that.....and we all then do nothing. That's not right, either.
It's very likely the civilisation we are currently part of will collapse in about 25 years. How? Drought reduces food and water. sealevel rise forces people to move....and the places they move to might not be very welcoming. Syria's collapse was a dry run and look at the trouble that caused. We will see movements much greater than that in the not-distant future. That's pretty much already locked in...and we're still actively making it worse. Most people alive today will still be alive then. Why they wouldn't want to avoid that......I don't know.
