We all alter time and space every day

To give you an example of what I mean let's take writing for example.

When writing was first experienced by Native Americans in Canada (Or should I say Native Canadians?) they called it something that would equate to "Black Magic" because it meant people could send detailed messages to each other in regard to culture, battle, spirituality, religion, love etc. and they couldn't win or compete or (communicate effectively enough) without their own writing. So, in wars and culture in regard to communication with millions of people they could not compete with the white people writing letters home to Europe telling people how good it was in Canada and the U.S. and to "Come on over". So, basically when they asked how many whites were coming the honest response was "As many whites as their are stars in the sky". The Native Americans and Native Canadians were not happy at this answer in the 1600s and 1700s.

So, the writing we non-chalantly do every every day alters time and space in ways beyond each of our imaginations because every being that reads whatever we write translates those writings to ideas in their minds and this temporarily or even permanently changes their lives in immeasurable ways.

This is just one way we all (Change Time).

Then let's look at mechanical contrivances like cars, trucks, planes and ships and tractors growing food all over the world.

There is a very good reason why the most people ever alive on earth is now because without oil (gas and diesel most people (likely 6 billion people would starve to death within one year or so.

However, with solar energy and water power this is changing very fast every day away from this particular problem to the point where in China and California the most efficient energy source is now Solar rather than any other source. And as gasoline and other fuels become more expensive this will happen eventually everywhere, especially as the price and efficiency of Solar cells increase just like microchips increased exponentially in efficiency even as their cost dropped between 1980 and the present.

IN fact, any way through education or direct experience we make more efficient decisions and actions in our lives (we change time) so we aren't like pets who accidentally get out onto freeways and get hit and die or like wild animals who become road kill. LIkewise, by learning how to survive in all the contrived devices like cars, motorcycle, trucks, ships and planes etc. we become more and more mobile and more and more efficient as a race of humans on earth.

However, that does not mean that there is unlimited room for more and more humans to be born and live on earth. So, in this way we are not efficient yet and until we learn to deal with this we are in danger of going extinct through not being efficient enough as a race through birth control.

It is possible we will become efficient enough once social welfare systems reach worldwide because then people won't have to feel forced to have 10 kids each to support them and to  take care of them when they get old in most of the world at that point.

However, to avoid extinction we have to find a way to get there before people get so upset that some terrorist nukes the whole world out of existence.
