Actually, the climate has no borders. Climate change is an international issue; not a country issue. If countries make selfish decisions to lower their emissions whilst boosting international emissions, where is the sense in that? I'd like to hear that from all of the activists who are pushing to get things like the Glenbrook steel mill closed here in New Zealand. The reason we'd want to keep the Glenbrook steel mill is our scrap steel can go the Glenbrook steel mill and be melted down and reused, and actually that's a lot less emissions because it's a much lower temperature than making steel from iron ore. So we've got to start to think about these things from a sensible, global perspective rather than looking at our own little area that we're in and not thinking of the bigger picture.
