Technology Altering Natures Plans

In the changing times that we live in more and more things are becoming 'accepted' culturally.  During earlier times if you could get pregnant then you just did have any kids but, now with the introduction of in vitro fertilization  wishes for children can come true.  Although this may be a miracle for them it goes completely against what nature was intending.  "Survival of the Fittest" is natures motto, where the fittest is regard as one that is able to produce viable offspring.  However, if the person/animal is infertile nature has decide to 'scratch' there genes from the pool of possible mixture of the next generation.  With the new technology that is allowing infertile couples to have children is going against the plan designed by nature.  Since the new technology is going against the "survival of the fittest" nature looks for other ways to slow the population growth.  

We see families such as the Gosselins or Octomom (very different situations) who have both used the in vitro fertilization methods in order to have kids.  In the case of the Gosselins, Kate had PCOS (Polycystic ovary syndrome) which made it so she doesn't ovulate thus making children impossible and therefore ending that genetic line.  As for Octomon well, she's single, had six previous children, and can have children naturally but didn't have a male to procreate with naturally therefore making her unfit.  In comparing their different situations you can see each ones need for IVF, that then draws the question of ethics.  Jon and Kate both had the standard amount of embryos implanted while Octomom had all of six or eight implanted.  Two different people using the same new technology where the outcome resulted in children but the thoughts of two families could not be more different.  With the power of the new technology we can have people who will abuse the use of the technology in circumstances where they aren't needed or where they did not have a stable mother-father relationship for their children.  

By using this new technology to enhance reproductive abilities do you think that this goes along with nature or is it our way of trying to one up the system that has worked in terms of evolution and progression in human kind?
