Where is the world going?

Keeping a blog updated is harder then it looks. My life just isn’t really that interesting and my literary skills are sadly lacking. So to that end, I will just leave you with a question, one which is breathlessly broad and seemingly futile to address. Of course, you should note that the one word responses just won’t do here. I want to have some valid reasoning to back up your claim. Sorry this is starting to sound like a philosophy exam. Ok, here she goes:
In general, is the world improving or worsening? … and why.
In school I used to hate when they added the “and why” to a question. You went from a straight forward answer to something which requires real thinking, a task which I never seem to feel like doing in the middle of an exam.
Based on pure gut reaction, I’m inclined to go with the former. Why? I’d like to think that the positive outlook is due to my nature, but strangely enough I consider myself to be a pessimistic person, and yet here I am maintaining that the glass is half full. Truthfully I don’t have any concrete reasoning for this perspective… at least that is a good justification for asking the question. So hit me with it. Are we all doomed to a future of decay, or will the “human spirit” (whatever that is) overcome?
