This is alarming ,it may not be that dangerous because we can't see the larger picture of the situation. Energy consumption in this year is continuing to rise up regardless of the price of BTC. 0.5% of world ENERGY is expected to be consume only by bitcoin. But the ideology of many people is "it is worth it as long as we get profit out of it" Yes it is correct that we get money out of it, but, will the environment be in danger for these? Well, Bitcoin mining can double a country’s electricity consumption and putting pressure on its infrastructure.

But how do we limit the damage to environment while still earning money?
-limit the impact of such energy consumption
There should be restrictions of using so much power on these mining equipment to every country to avoid energy shortage
