Our Grandchildrens World

I often wonder what the world will be like when my grandchildren are my age. Will the air be too polluted to breathe? Will we have solved world hunger? Or perhaps, with all our superior knowledge, wisdom, and technology, simply have destroyed the earth as we now know it? 

Tragedy is usually what seems to unite a nation; 911 proved that well. But, what will it take to unite the entire planet? What can possibly put us all on the same page so to speak? Would a terrible, unstoppable disease cause us as a race to band together? 

What about first contact with an alien race? That would be an eye opener for sure. Right now our two main problems seem to be religion, and greed. Greed is running our nation while radical religious freaks are taking control of the rest of the world. Common sense seems to be a thing of the past. Yes, I am very concerned about our future generations well being. It doesn't look very bright at this time. What is your take on this matter.
