I'm shocked and disheartened by how infrequently environmental concerns are brought up when discussing crypto. Proof of Work vs Proof of Stake, security, storage size - these are problems for the network and those that want to see it become a real part of our economy. (I am one of those) But the amount of energy being used to mine bitcoin is a real problem - it's not just a technical challenge (like the problems abov…
Bitcoin is one way to use energy. There are hundreds of thousands of other ways.
When you say Bitcoin "hurts the environment", what, concretely do you mean? Presumably, you mean it in a stronger sense than "using energy to produce food hurts the environment" or "using energy to run an ER hurts the environment".
That is, you think that relative to the benefit provided, the use of (harmful) energy to run bitcoin miners doesn't justify its environmental cost.
Which is great, but I could say the same thing of Ferraris for show-off producers in LA, or Hello Kitty backpacks.
What justifies focusing our attention on Bitcoin per se, and not those? Do you plan to publish a universal, agreed-upon list of things whose social value doesn't justify its environmental cost?
The real problem is energy users not bearing the full environmental costs of what they do.
The thing is, we have a well known solution to that: cap the total carbon emissions, or tax them in a way that reflects the harm.
Yes, Bitcoin creates an incentive to use energy. And it will be spent by miners who weigh the costs of the energy against the value of the Bitcoins produced. Like every other good on the market, it will respond to incentives created by laws.
If the damage of energy isn't priced in, then there will be too many resources spent on mining relative to the environmental cost. But this is true of every other good as well.
All Bitcoin does is amplify the problems of the existing failure to appropriately price energy. But this is true of literally every other energy-using good in existence!
There is no reason to single out Bitcoin. To blame it for environmental problems is special pleading or privileging a hypothesis.

EDIT: Should probably add the disclaimer that I'm long Bitcoin.
