New But Is It Improved?

So I came across this post in the msn news feed today http://slate.me/pzmQ1A it is all about enhancement of our environment and focuses specifically on human enhancement.  Now humans have tried our best to conform the world and environment to our preference, but in the end, nature keeps on winning.  For example, bacteria and viruses keep getting stronger, each year we have to take a guess at a new flu vaccine.  Despite all our technological advances we cannot even combat a simple flu virus.  This article talks about the various ways humans have altered themselves to be their ideal, but with nanotechnology blooming what could happen next?  When I hear the word nanotechnology I envision microscopic robots being inject into us to purge our bodies of infection an disease...  Initially this seems amazing, but then I think a little deeper.  How do these nanobots know when to stop, what is preventing them from attacking healthy tissue, what else could go wrong?  Right now, I'm holding onto my faith that nature still has made a better solution, we humans just haven't found ways to utilize it. 
On the whole humans are extremely narrow minded, we see the world as something to conform to our own will, instead of looking at ourselves as one part to the whole.  We may be influential, but in no means do we control everything.  Control shouldn't be a main goal.  The objective should be to work in harmony with the world and use our power/influence to help it excel in a manner that will allow humans and many other creatures to live for the longest duration possible.  All organisms on this world have a finite lifespan, even our world and sun will eventually die.  This is simply natural order.  In contrast it is also natural for all organisms to want to live as long as possible in order to propagate as many offspring as possible.  So how do we battle these dueling pre-sets within ourselves?  A big question that truthfully I don't think anyone has a certain answer.  A few things are for certain, humans will continue pushing their bodies and technology to the limit, nature will continue finding ways around it.  Other than that it is all variable.  To be continued...
