The amount makes the poison - even with CO2.
In the last few decades, due to human activities, too much CO2 has entered the troposphere of the earth, it stays there for a long time and acts as a kind of seal, so that the heat from incoming sun rays can no longer be dissipated to the outside (greenhouse effect).
The life and survival of many people worldwide is endangered by the rapid, short-term heating of the earth (droughts, hunger, natural disasters), since such rapid anthropogenic adaptation is not possible.
For this reason, we should reduce CO2 and other greenhouse gases such as methane as much as possible - #Bitcoin can help here in many ways!
