Bitcoin mining is not depleting our ecosystem, it's not the cause of green house effect neither is it the cause of climate change.
The majority of the user in forum knew this and government is just using the greenhouse effect blaming on crypto since they can not shut it down and they just want to make a negative image on Bitcoin to the public so that they will be discouraged to use it.
We are all here because we have self interest and that kind of feeling makes us mutual to each other aside from what you point out connection. This is my simplest analogy on why we are all gather here in crypto space asides from the privacy thingy.
