It’s not one specie of dinos that lasted hundreds of millions of years.   Rather it is thousands of descendant species of Dinos that each came and went in its own time within those hundred million years, rather like individual bubbles come and go within a persistent head on beer in a glass, that kept the genetic lineages of the original ancesteral ur-dinosaur going all that time.

Even if our descendants are still in existence a hundred million years from now, we as the ur-sapien specie need not ourselves be particularly long lived and avoid extinction for all that hundred million years.   We could emigrate from earth and quickly and prolifically speciation, leading within a few million years to many daughter species of human descendants better adopted to a wider array of environments and technology conditions, while we the original ur-specie either linger or go extinct.    Some of our daughter species would in their turn spectate, but all of them will also go extinct sooner or later but mostly long before the hundred million years is up, leaving our genetic future in the hands of yet more generations of grand daughter species.

 Colonists who don't live environmentally sustainable lives will trash a new world in just a few hundred years.

That;s why we need to pick a planet where our pollution is a pro, rather than a con.  Someplace that could use a shitload of global warming, someplace that might benefit from piles of organic and inorganic material laying around.

Or, and I think this is more credible in the near future (as in, anytime in the next thousand years, lol)..we can practice our terraforming chops here, on the world we already inhabit. It's an old girl, she could use a new bathroom, kitchen has to be updated, you know the drill.
I am the Infantry. I am my country’s strength in war, her deterrent in peace. I am the heart of the fight… wherever, whenever. I carry America’s faith and honor against her enemies. I am the Queen of Battle. I am what my country expects me to be, the best trained Soldier in the world. In the race for victory, I am swift, determined, and courageous, armed with a fierce will to win. Never will I fail my country’s trust. Always I fight on…through the foe, to the objective, to triumph overall. If necessary, I will fight to my death. By my steadfast courage, I have won more than 200 years of freedom. I yield not to weakness, to hunger, to cowardice, to fatigue, to superior odds, For I am mentally tough, physically strong, and morally straight. I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!

As a species with technology, we are not subject to intense natural selection, and so, our present form may last for millions of years, and be maintained via sexual selection only.

I don't know. By intense natural selection, you mean that death isn't doing the selecting anymore. We don't know what the fallout is going to be from that.

We certainly are. Natural selection swinging the composition of the gene pool in populations leading to speciation often is a very slow acting and subtle influence When compared to the time scale of the life of a single individual, and usually lacks any of the swift and dash imagery conjured up by “red in tooth and claw”. But it is natural selection nonetheless and continues to act on our population. If your lineage on average produces 1.9 live offsprings and 1.8 of them successfully reproduce, over hundreds of generation your genes would be at a massive disadvantage compare to another in the same population that on average produces 2.0 live offsprings and 1.9 of them successfully reproduce. All things being equal Over time the gene pool of your population will show ever more contribution from the other lineage and ever less from yours, just as over a few minutes lions might cull the genes of slow antelopes from the gene pool.

Death is itself irrelevant to selection. Reproduction resulting in offsprings whom themselves also reproduce is what counts. Whether the selection is natural is also a matter of arbitrarily drawn boundary. We are certainly still undergoing going processes that create vast divergences in the rates of successful reproduction in different parts of the population. So the gene pool of human population is still undergoing intense selection.

Religion - where logic goes to die.

Mother Theresa was a monster.

She raised millions of dollars and the conditions never improved for the poor patients, in a country where stuff cost next to nothing. She was a con woman who spent the money on nunneries instead of the hospitals she was given it for.






You can fix ignorance, you can't fix stupid.

Tinkety Tonk and down with the Nazis.

Within 80 years, a death toll of 6 billion 930 million all due to climate change and the extreme warming of our planet.
And this is the conservative estimate.

My grandson is 8 years old. Will he live to be 88 ? What will his life be like ? Fuck what will mine be like. I still have a good 30 years left in me.
The 2C degree change is already locked in. We're now talking a 6C degree change by the end of the century.

Extinction seems inevitable.

Do you think other countries will attempt to drastically eliminate those problem countries in order to save those nearly 7 billion lives on the line ?
Would you kill a billion people to save 6 billion ?
Would you kill 3 billion to save 4 billion ?

That's a bottleneck of death I'm not quite ready to even think about and yet it's in our immediate future.

I'm an alarmist when it comes to this stuff. I already know it and accept it within myself.
Maybe when I'm 60 or 70 I'll calm down a bit.

We might see the end in the millennial generation if we go past that 12-year time window. 
12 fucking years we have to curve our use of fossil fuels or well... bad things happen.
It angers me that no one in the U.S. is taking it seriously because.. well there goes huge parts of Florida,
the eastern seaboard, washington dc, new york, etc. Then you have the droughts, war for fresh water, 
the world seems to get smaller as the issue of immigration gets even worse when people look for land. Not to mention
the middle east huge parts of it get uninhabitable for human life. Then desertification gets even worse and the ocean turning acidic...
this is enough for anyone with any sense of danger to say we should change how to produce energy. 

I am being cynical about anything happening as for how we change to green energy because we a president already that could have done it and we have
a president that doesn't believe in climate change.
Atheism is a non-prophet organization join today.
