Bitcoin is not controlled by anyone since it's decentralized but when I say bitcoin I am referring to the bitcoin community and it's not individual donations but as a community and it's not just a matter of time but rather how we create impact on lives and betterment of this world. If we can form a community and donate then it will make a difference, yes the identity will be anonymous but still it will be from bitcoin community.
Yes, maybe that will provide something more beneficial for the environment. But does every bitcoin user need to pay attention to the environment?
In my opinion to pay attention to the environment one must realize that the environment is the most important thing in the life ecosystem. Building a charity community is a very appropriate thing in my opinion, and not only crypto users but the government must also be involved.
