Wut? GW is a proved fake. Even pro-global-warming "scientists" already agreed to change its name to "global climate change" since everyone sees that it's total crap. There were always periods of global warming and global cooling and they will always be. It has nothing to do with us. Especially with mining.
Really, what planet do you live on, not earth.
Yeah, we should probably downplay the "carbon footprint / global warming" thing. The global warming ship has sailed, fewer and fewer people believe in it as time goes on.
We CAN say that Nxt "conserves resources," as that is not up for debate and the people that still believe in global warming can make their own connections to carbon footprints and what not.
It's funny, but 20,000 years ago, in the spot right where I am sitting, there w a glacier two kilometers thick. Now it's melted and the nearest glacier is 2200 km away. I used to blame that on carbon emissions from the industrial revolution, but people kept laughing at me, so I became a climate change denier.
