My thoughts are that although Bitcoin uses a considerable amount of energy, when related to climate change and its impact on the environment it pales in comparison to other industries burning of fossil fuels, as well as deforestation and farming. Furthermore, because Bitcoin is reshaping global finance, I feel that it will be around for the long term.
These are my thoughts exactly, Bitcoin's footprint is really tiny compared to things like cruise liners or agriculture, so people who want to stop Bitcoin because it causes global warming are likely just being misled by nocoiner trolls who spread all sorts of negative information about Bitcoin. It's especially ridiculous when they say that Bitcoin will soon consume all the Earth's electricity, just because it's energy consumption was growing in the past very quickly. In reality it will slow down significantly because of the halvenings.
