Human Evolution; Extinct? Part Three

As I said earlier, I think that human evolution is done on a physical standpoint for several reasons, unless we have some sort of cataclysmic event that causes natural selection to start weeding out some of the population.  Now where does this leave humans?  The idea occurred to me that maybe we were experiencing evolution on more of a social level about 2 weeks ago, when I realized that some people were actually not having children due to their various problems.  A key example would be my friend.  She has a lot of issues, both physically and mentally.  She is determined to not have kids because she doesn't want to pass on these problems to her potential kids, as this would be unfair to them.  Maybe it is now up to the individuals to pass on their genes or not, so now maybe the "natural selection" is our own social consciousness.  Now don't get me wrong, not everyone is socially conscientious, in fact, I believe the vast majority of the populous is not.  If everyone were to be considerate and conscientious about the society as a whole, and not what is best for the individual, we might actually see a significant evolution of sorts.  This problem can be explained with a little bit of advanced economics.  There is this theory called the tragedy of the commons and to explain it, lets say that there are several fishermen and a supply of fish that they can all fish from.  The individual fishermen will do what is economically best for them, so the vast majority of them will fish.  For every fisherman that decides to fish, the total marginal benefit, or profit, decreases for all fishermen.  After a while, the fishermen will deplete the supply of fish, even though none of them intended to so as it is not economically beneficial to any of them.  If they would have worked together, the total benefit amongst all fishermen could have been achieved, and the supply of fish wouldn't have been defeated.  The moral of the story is that we as a society need to work together in order to receive the most benefit, as most individual working on their own will pick an inefficient solution that could produce a lot of harm in the long run.
