You can't save the planet, planet will always undergo changes. That's the reason we have different era/age. Things will always change no matter how you keep it that way. Accept the fact that the only thing human can survive is to find another planet that is most likely the same as Earth.
This ^^^ is an example of the real problem of people. Here it is.
Nobody really cares about survival of the human race. Most people who act like they do have been programmed to think like this in school. Rather, everyone thinks about himself and close friends and family.
So far that we know, nobody survives physically. ALL PEOPLE are lost The few people who live longer than 100 years, don't live much longer. And usually their quality of life is way, way down.
People should be looking at the spiritual aspect of things, to see how to let their spirits survive after physical death. All this racial heritage stuff has been created by shrewd people who are trying to use it to gain control over other people.
