Its just a question nothing to worry about.
Im not worried. Im past that. What frightens you and what excites you about the deterioration of our life on planet earth since we are killing off the environment that supports the economy and life overall.?
We are not killing off the environment. We do not possess the powers to truly destroy this planet, not yet. For that we would have to be at least a Type 2 Civilization.
I'll explain what this means since terms like type 1 and type 2 might sound very confusing to most people.
There are
7 Types of Civilization in reality, it is explained in a scale of levels called the
Kardashev Scale.
Type 0 : Stone Age - this is the phase at a which a species begins, people living in huts/caves, creating fire etc etc ....
Type 1 : Planetary Control - An advanced species that is capable of extracting every power in its home planet, i.e not just solar energy, wind energy, water, nuclear .....This means everything, even the earth' core we should know how to generate energy from it.
Type 2 : Solar System level control - A species which can extract not just power of the earth, but also from the sun that provides it. That means structures called Dyson Spheres shall be built around the Sun to control all its energy and of course we will be able to control the other 8-9 planets as well.
Type 3 : Galaxy level control : A species which has evolved to such a level that it can control the entire galaxy it is in, lets say Milky Way Galaxy that we are in. We have control over all the stars in it and all the planets, that would be Type 3 level civilization.
Type 4 : Galaxy Supercluster level control : A species so advanced that it is good enough to harness and control the energies of a cluster of galaxies. At this level creating stars/planets would all be child's play for the species.
Type 5 : Entire Universe level Control : A species so advanced that it is capable of harnessing the entire powers of the universe it is in. This means the species (humans in our case) would have evolved to such a degree that it can travel to other universes back and forth, laws of physics can be altered and manipulated. At this level creating galaxies or destroying them within your own universe would be child's play.
Type 6 : Multiverse level control - Now You control all the different universes that exist in your multiverse and you also can create/destroy a universe a will. Big Bangs can be started and ended at will here, it means complete mastery of all universes within the multiverse.
Type 7 : This level exists outside the multiverse. That means outside the realm of existence - GOD exists here, Truly Omnipresent, Truly Omniscienct, Truly Omnipotent.
Now coming back to where humans stand in 2023. Scientists estimate that we are currently at Type 0.7 on the Kardashev Scale and by the year 2100 AD we shall reach Type 1, and then it will take another 700-800 years to reach Type 2..... After that it might take another 100,000 years minimum to reach Type 3. A typical Type 3 civilization would be what we see in Star Trek movies where we have the power to travel from 1 star to another star at Warp Speeds that approach the speed of light.
It is said in the Sumerian tablets that GOD (an advanced race on the K Scale) came to earth 200,000 years ago and created the first man (Abrahamic religions call it as Adam, hinduism calls it as Manu, but it all the same), that was probably first of the many apes who were created by aliens by genetically mutating the DNA and giving us extra intelligence to progress faster. It is said that we were created as slave species for mining gold.
Now we come to the answer to your question, we are not capable of destroying the planet, if our attempts at tinkering with the energy levels of the earth go wrong by 2100 and we don't have a backup planet then we shall not reach Type 1, we shall perish. The planet will live, it will heal itself like a body heals itself with fever and kills the virus/parasite that it hosts.
Then what happens after we are extinct ???
Our gods (probably type 5 or above) are watching us and they shall once again come to earth and "terraform" the earth to create/facilitate the rise of a new species, maybe not man ? Something else this time ? I don't know, but what I do know is that the earth is in no danger from us until we reach Type 2, it is the we who have to worry. Gods are watching us, they are not interfering as of now, 1 giant asteroid is what it shall take to wipe us like they wiped out the dinosaurs 65 Million Years ago. The Great floods happened and Noah's ark saved humans, right? Who send those asteroids/floods? It is our Gods.
So don't worry about global warming or population explosion, just have kids, try to teach them to survive & to be scientific, rest will all happen as per God's plan or based on natural selection.
But having kids is very important, that is why God created us 200,000 years ago so that we could keep on progressing on the kardashev scale, thats the aim of human life on this earth.
