The times, they are a-changing.

Since Gregor Mendel unwittingly became the father of genetics by writing down his botanical observations, we have been progressing along swimmingly in our understanding and application of biology.

In the past few years, we ourselves have made some measured leaps forward in the field of biotechnology, some small someless so. Yet with the monumental achievements we have made thus-far from the advent of vaccines to our understanding of how our bodies age and degenerate, we have yet to make that quantum leap forward. That quantum leap may itself not be that far off and if anything is a good indicator of that its observable in the nature of the biotech we are currently developing.

With any huge leap forward, however, come new challenges and a slew of new questions that desperately need to be answered.

This next step in our journey isnt quite like when we eradicated major diseases or began transplanting organs because it isnt about extending human life a mere few additional years. We are taking about a doubling in the years a human may live. Thats right, double.

Now, before you write this off as sci-fi or wishful thinking, let me walk you through exactly what breakthroughs are currently occurring. It all has to do with CRISPR gene-line editing and 3-dimensional printing.

We are at the point where we can take normal somatic cells like the ones from your skin, coax them back into stem cells then re-engineer them into just about any type of cells we want. This means shortly we will be able to take skin cells and make them into heart tissue, or liver, or pancreatic or any number of different ones.

Next, the advances in 3-dimensional printing may shortly be able to take your newly minted cells and print them onto a blank scaffolding in the shape of just about any organ you may need.

Think of that: if you need a new heart it could be as simple as scratching some skin from your arm, reprogramming the cells and then printing you a whole new organ. Not a transplant from a donor, your own cells. This means no rejection and no waitlists. When an organ fails we replace it, again and again and again.

What is to become of a human race that is capable of living seemingly without end? This brings up some serious questions that would have to be answered quickly.

For starters, we see that the current population growth of our species is unsupportable as we resist green energies and advanced farming methods. If humans were to begin to live twice as long or longer we must figure out what we are going to do.

Now the radicals would suggest we simply control the populations but I dont believe that is necessary or even morally right. All we must do is increase our carrying capacity. I must admit that was not my own musing but one my father suggested to me.

If we are able to increase how much food and energy we produce without damaging the planet there is virtually no limit to how many humans can live at once. But the question is, will we resist it as we are now? Will the prospect of living healthily well over a century spur us to begin to accept scientific consensus? Or will we continue down our current path of selfishness and greed? Only time will tell.
