I think human emotional state is nature's tool to get us to procreate and improve the chances of our offspring to survive. If at anytime we become truly happy this hurts these goals. For example, if an old man could be building a wall or an arsenal of bows an arrows, or inventing a better way to go fishing, his tribe would be more likely to survive. But if he just sat there, content to being alive, this is bad for hi…
What if the human emotional state is a byproduct of human consciousness. In that way, it isn't something that can just be chopped off as unnecessary. Not to say that it doesn't help with procreation but I think your view point is a little too cynical. What does this suggest about people that don't have kids?
I have no idea what “human consciousness” is. I'm not deriding you, but I have never heard a satisfactory explanation. I kind of suspect it isn't actually real.

There are a lot of species of wild animals that will not procreate in captivity. Take a group of these creature that is adapted to a certain environment and then place them in a completely different environment and they will for some reason lose their will to procreate even though they are physically able to do so.
I think it's the same with human beings. Technology has pushed so far and fast away from how we used to live, some of us, for whatever reason, don't procreate anymore.
