Crypto mining are causing massive destruction among nature resulting in thick layers of toxic smog and blackout. "According to a Bloomberg report, the energy requirements of Bitcoin (BTC) and crypto mining in Iran coupled with the demand for heat in an exceptionally cold winter have contributed to a natural gas shortage, forcing power plants to allegedly burn "low-grade fuel oils" to meet the country’s electrical needs. The result has been "thick layers of toxic smog" across many Iranian cities and blackouts as some power plants have closed."
