Some people I've spoken to view this as on par with not supporting the All Blacks. To top this off, they typically have an irrational fear of nuclear power steaming from pop culture such as The Simpsons.
It's New Zealand's dirty little secret that we're no where near the "100% pure" ad campaigns we're running. Half our rivers are polluted beyond repair. We have less forest coverage than Japan. We flooded vast tracts of land for our dams. And we're still dependent on non renewables for our electricity.
There is an ebook  extolling the virtues of Edo society, and while I think you have to take it with a grain of salt (it paints a very rosy picture), it is very interesting.
I noticed another book  which looks like it would be an interesting read, but I haven't done so yet.
One of these days I'd like to learn more about current forestry practices in Japan. I live in Shizuoka prefecture and I see some areas cleared occasionally for tea fields. Also, some of the cedar stands are threatened by invasion from bamboo and you can sometimes see them trying to clear the bamboo and replant cedar. But firewood is currently so cheap that you can often get it for free in my area, which worries me slightly.
Japan has forest coverage of 67%, which is very respectable. New Zealand has 31.87%. Next 3 countries after New Zealand are Germany, Canada and United States.
