Aside from the rewording/repost from an article that you did, if you are really interested in looking at the carbon footprint of mining what do you propose? Have you looked into how "green energy" can improve the mining carbon footprint? Have you looked into new ways of mining hardware configurations? The point of the article was to say that mining takes a lot of energy, your rewording spouts that mining takes a lot of energy without giving anything back. What's your solution if this is your way of thinking?
