Humanity don't need such high consumption and waste of resources only because some smart asses want to have nice economy growth charts. Time to change whole system and the way people are thinking about what they really need.
High consumption and waste of resources steams from misappropriation of money. I'm not even remotely trying to suggest that miners go loose with their spending sprees and start financing government projects that the central banks are so in love with. The beauty of bitcoin is that those with the mining power behind them get to decide which projects to finance, be it all-inclusive resorts in the Bahamas, a lemonade stand on every 10 mile block along the favorite bike route, or
a nanotechnology breakthrough.
