Thoughts on human utilization of energy sources such as oil on the earth

Based on the level of human civilization and the total amount of energy that can be mastered and utilized, Nikolai Kardashev, an astronomer of the former Soviet Union, proposed a three-level model of cosmic civilization. The first-class cosmic civilization has the ability to exploit and use almost all the energy and energy on the planet, control the weather, land and various natural phenomena on the planet, and fully grasp the use of planetary energy. According to this index, the index of human civilization has reached 0.7 of the first-class cosmic civilization.

Biological deposits billions of years ago into oil; Ten thousand years ago, the ancients drilled flint for fire; Two thousand years ago, there were records of human use of oil; More than one hundred years ago, people began to use industrial methods to mine it from the ground.

After entering the human age, people took themselves as the coordinate center and made every effort to make use of oil in the most correct way they thought at that time.

Human beings turn most of the crude oil into fuel, burn and do work to drive locomotives, which promote human activities all over the world; The carbon emission after combustion produces greenhouse effect, which endangers human survival. A small part of crude oil has been turned into chemical fiber and plastics, which are used in clothing, food, housing and transportation; It takes hundreds of years for chemical fiber plastic products to degrade after being discarded; Plastic makes people stop connecting with life and natural environment, and more with dead substances.

Is what humans do on this planet on which we live really the right way to develop civilization?
