Also, bitcoin transactions require barely any electricity at all, it's bitcoin mining that wastes valuable resources that could be more productively used on nearly anything else.
Except bitcoin mining is inherently tied with transactions: https://www.bitcoinmining.com.... bitcoin mining is how the transaction system works, verifying each transaction. The system blows through cheap energy to make fake cash. The whole system results in a massive waste of energy for an inefficient currency.
Just because something is unsafe, doesn't mean I want to stop doing it. Sometimes it's worth doing so long as it can be done more safely.
The problem is, it isn't being done safely. The industry routinely has spills which do lasting damage to the environment, and the industry has a death rate that is 7 times higher than all other industries (http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6216a2.htm). This is beyond the day to day pollution caused by the oil being pumped out. I'm not saying we can avoid this, but it's a shame we continue to look the other way.
