Critics overwhelm the Crypto Mining Industry on POW blockchains. Although BTC runs the safest blockchain, it's the most polluting one.
Mining companies can make Thousands if not millions of dollars with almost no employees.
Mining companies can provoke problems in their communities due to the amount of energy usage.
How can we make Mining Operations more sustainable?
Redirecting part of profits towards the problem they cause? Eg: Sustain or fund environmental impact businesses.
Going 100% solar/renewable energy?
How can all the critics be countered? How can we create an ethical mining sector?
Bitcoin mining is probably considered as a business which can garner large amounts of income, given the right resources and location of the plant. Although the presence of miners have been continuously increasing, news spreading about its environmental effects are also starting to manifest.
Like what most people have mentioned, one consideration can be shifting its power by to renewable/natural resources for its energy. Many countries practice the use of maximizing their natural resources and converting them to power depending on their geographic location.
Another consideration can be by setting a limitation or cap on power.
I guess the safest way to address the critics is to provide a framework about the proper disposition of pollution. The task is relatively difficult but it is definitely achievable with both sides benefitting.
I personally don't buy any of this stuff about mining causing such a huge problems when it comes to electricity usage and pollution. There is far more and far worse industries that spend much more resources and pollute much more then mining will ever be able to do.
Of course it would be best if mining could be done only using renewable energy source, but if people worried so much about pollution and energy efficiency we should first turn our heads toward other much more problematic industries.
Many of the industrial problems are caused by companies who monopolized a certain industry, which the general public rely on. Although the waste that they produce certainly affects the environment, the government cannot simply penalized them without giving compromises. Mining, on the other hand, is a relatively new type of business which is on its embryonic stage. From this standpoint, the pollution can be controlled by introducing techniques which can lessen its detrimental effects.
