>"But the amount of energy being used to mine bitcoin is a real problem - it's not just a technical challenge (like the problems above). This is something that literally affects every human being ... But we need to talk about the environment." Great, put it in context then: A. What is the total energy content of the resources consumed each year? B. What percent of A is lost to "waste" such as powerplant and grid inefficiencies? C. What percent of the remaining is spent on crypto? D. What other things are consuming the same order of magnitude or higher than crypto? E. Which energy use described in D is easiest to make more efficient without harming the purpose/quality? Then improve #1 discovered in E until it is below #2, then start work on #2, etc. I think you will find stuff like getting everyone to use i.reddit.com instead of reddit.com and netflix to stop their annoying auto-playing previews should come before anything to do with crypto.
