There are some questions or threads we see here mables me. What bitcoin has to do with environment again? Bitcoin is an online or a digital currency which can be used to buy goods and services and if the service providers accept it. so I don't see any connection between the two. But if you understand bitcoin you would not ask such question. What your Fiat currency can do bitcoin can also do if only the environmental service agencies will accept it then bitcoin can be used.
I am a biological scientist maybe i don't understand bitcoin as good as many here, but i understand 2 things.
The biggest challenges of our generation is environmental issues and much of it is human waste and emmisions.
Currently there is no real rewards for waste management and and secondly bitcoin mining..( not trading or transaction)needs lot of energy. If we can club them together can't we mine bitcoin using otherwise useless waste..
Thankyou
