no species is forever

Because the environment of earth is constantly changing there is no one species that has remained exactly the same for millions of years. The same is true of human beings.  Relative to many other species we have not been around very long according to recent studies. In the forms we are presently in we likely have not been a lot like we are now even 50,000 to 100,000 years. Intellectually, culturally and physically we have been constantly changing.

Even since I was born around 1950 people have drastically changed from what people were like when I grew up. When I grew up all races were very ignorant of each other for the most part and so everyone was much more racist than now. I'm not just talking about white black racism because for example, people from England might say bad things about any other European nation and any European nation might say bad things about any other European nation and this still goes on more between lower class people of nations worldwide who are less educated still even though more educated people worldwide tend to be less racist and less ethnocentric than before especially people who have traveled the world alot like myself.

But, to put this in perspective only 30% of people in the U.S. even have passports. So, this says something that would horrify most Europeans who travel much more between countries and usually speak 2 to 6 languages as a matter of course if they are educated. Here in the U.S. even speaking two languages is rare unless you are from another country and unless you have been to college or are planning to attend college.

Then you have people's behaviors and diets in addition to this. For example, when I met Nepalese porters who carried people's goods where there were no roads at all in the Himalayas they would often marry at 15 and by 40 or 45 they would be burnt out or die by 50 because of the hard work at altitude.

Even today there are places like Russia where most men because of Vodka and other alcohol and cigarettes often die before 55. So, what you think, what you eat, what you do, where you go often decides whether you live a long time or die and this also changes genetics as well as behaviors of succeeding generations too all over the world.

IF you were to check life spans in Syria and IRaq right now you might see the general lifespans greatly reduced, especially among those who are refugees. Their average lifespans might be 40 as an average or lower if such a poll could be taken including all those who have died. It could even be lower than that if all people were included that were killed or starved to death or whatever.

So, the kind of genocide presently happening and the refugee crisis could now spin out of control like it did during World War II and cause the deaths indirectly of millions more people like World War II did when around 100 million people died worldwide and then 100 million more died in the Cold War worldwide between 1945 and 1990.

All these tings affect genetics and who lives and who dies and what genetics get passed on in the human species. And these kinds of wars have gone on for thousands of years already. People say this is survival of the fittest. But, my point of view is people who avoid wars live and the rest often don't.

So, the people who don't live often have no genetics that are passed on down the line. All these things affect the future survival of the human race too as well as any animal species that go extinct or forests that are blown up or cut down  for any reason too. Melting Arctic or Antarctic regions are also going to decide who lives and dies and even things like the ZIka Virus could decide who lives and dies and what genetics are passed down as well.

So, will humans survive all this? It is likely that some will even if they have to move to another planet to start over again.
