To be honest, it is almost impossible for any current innovation to consume energy without harming the environment in some way. We are living in the generation where time and money is more important than the environment for us but I am happy that the steps are being taken to reduce the percentage of damage to the environment. Mark my words, we will start taking care of the environment at the point when it will start damaging us in some way in the form of returns. This issue is not limited just with Bitcoin or crypto industry but it needs the macroscopic approach to deal with it on a bigger level.
