One of the problems with human reasoning is to imagine that we are significant to the natural process of life.
Hahaha, delusions of grandeur.
Just for a second, a considerations, is it possible that humans, existing for a mere 2 million years might have no idea what is really going on in a Universe that has existed for 14 billion years or so?
How could any person understand what is really going on?
Bur wait, put yer ego aside for a second.
The question to ask is why?
Why, in the world would we, who can't understand our own brains or the planet we infest, why would WE be so freaking special we have all the answers?
Sorry, that just makes ABSOLUTELY no reasonable sense?
So lets just say, we are infants learning the world in which we inhabit.
Lets figure that everything we know, all we have 'found out' about the Universe is but an infants view on the actual reality out there?
What happens then?
What if what you think you know is not what is actually happening but only how we understand it according to what we have learned so far?
Our reasoning approximates about 2,000 years, Pretty significant to a species that lives about 100 years.
The Universe approximates to 13.8 billion years.
Do you even realize how many 2,000 year periods are in 13.8 billion years?
The significance is the determining factor not a strange detail.
We Know NOTHING!
Hell, ya can't even control your own population, understand your own planet or contemplate the vast dynamics of the Universe in which you exits.
2 million years your species has been around.
Eventually, some far superior life form will consider Humans as a short lived fluke in the evolutionary past of this planet.
LOL, talk about delusions of grandeur!
While our type of star is pretty common it is not the only type of star out there.
The most common star is nothing like our Sun.
Some stars only exist for millions of years, others billions of years.
Some stars are so radiant, no life can exist anywhere near them.
Some stars expire long before life on any planets can occur.
Plus, there are a million other variables that prevent life, let along advanced life from ever happening in that star system.
The G2 type star, being fairly common, also is not a guarantee that life or advanced life will form in its system.
There are systems with multiple stars that prevents the stability needed for life to advance.
There are stars with too much or not enough radiation to allow advanced life to mature.
Our own Sun and the system in which we inhabit has just the right combination of conditions that allowed life to mature over 4.5 billion years to create us.
Sure, there might be other G2 systems that create advanced life.
There is nothing to suggest those systems are exactly like ours and results in exactly the same way as our planet did when we evolved.
There could be greatly advanced life forms or greatly inferior life forms but all those life forms are unique to their parent star system.
For a random G2 star to produce a civilization we could even call our brothers is astronomical and likely 1 in 1 billion or more.
Lets say everyone suddenly became aware of the environment, all 7.7 billion of us.
Lets say each of us dedicated themselves to stop environmental damage in everything we do.
You no longer flush your toilet because it contributes to the erosion of the natural environment.
You stop using electricity.
You stop going to work, driving your car, flying, using manufactured items.
You stop eating, exercising and moving around.
What you can't grasp is not the impact you are having on the environment by just living, you fail to realize you are not the only one.
7.7 billion others are on this plane right now, making more.
All the things you 'need' in your life are there because something or someone is affecting the environment.
The plastic you use requires raw material being harvested, chemical processes to make it plastic and work forces to mold, assemble and distribute it.
All the people doing that, also depend on the same things you do.
You recycle your plastic bottles, oh wow, that makes a big difference in the actual reality of the impact. Someone gathered the recyclables, hauled them to a recycling center, sorted them, moved them to the recycling processing places and ran the furnaces and all the resultant processes needed to bring it back to you.
People, more people. All creating more waste than your little bin of recycled plastic saves.
But, you feel better because you did your part?
The environment is interconnect with everything you do as long as you live.
Times 7.7 billion.
Plus, there is the natural planet processes that have been occurring since the Earth formed.
Want to make a significan't gain in environmental recovery?
Remove about 4 billion people from the cycle.
The Earth will not end.
It will recover.
Faster without us but it will no matter what.
People think we are destroying the Earth but all we are destroying is our world.
There is a difference.
Ever notices how weather sites label storms and conditions with terrible names?
Stormageddon, Worst heat wave in the last decade, season of storms.
Its all designed to get the public frenzied about things that are naturally occurring.
Oh God, we're all gunna die!
Sells papers, air time and website hits.
Just this week I read how the northeast was in for record breaking triple digits heat for days.
I talked to my sis, who lives there and yeah, its summer hot but not so bad.
We are TOLD something but reality unfolds as something else but hey, it reaches 100 degrees on one day so people think oh, its all true.
The term for that is SHEEPLE.
I'll bet they sold a lot of air conditioner units in the northeast last week.
I'll bet the electric company inflated their cost per kilowatt during that time and people think nothing of it.
Oh, and right now, there is a 30% chance a storm could turn into a tropical depression off the coast of Florida and people get all worked up about the "Crazy" weather nowadays.
LOL, have fun with all that media inspired stress.
