“Climate change” is the distraction phrase. It’s obviously more efficient to use a blockchain to determine who owns what. Banks with all their employees and buildings, use more energy. Plus, the cost of energy is falling as renewables continue to advance. Pitting Crypto Currency against Climate Change is a way to win over the less informed. People vote against their own self interest all the time. Just need to tell the correct lie to people and you can get them to do whatever you want.
