Honestly, I can't see how the world can get any worse. There is war all the time. And the span of time between wars is never very long.
Think about it. In the 20th and 21st centuries alone there have been hundreds of wars. And for major modern day wars, there have been 21 already. By modern day I mean since the middle of the century, the 1950's.
The longest span of time between two major wars in the 20th century was merely a scant 8 years. And most of the wars started since the 1950's where only 1 or 2 years apart. This 1 or 2 years is the time span between when the wars started, not between the end of one and the start of another. So many, many times, there has been more than one war going on at any given time. Hell, the Cold War was about 40-50 years long.
Are humans really that violent a race that we can't even go a decade without starting a war? If we're this bad now, imagine what it will be like farther in the future. If we even meet intelligent alien life, the first thing humans will do is probably going to be to declare war on that other species.
I'm tired of this constant never ending war. Why is it that humans are so intent on killing each other? If we just put down all of our weapons and worked together rather than against each other than we'd be able to do anything. If we took all of the money spent on war and used it to solve world hunger, stop global warming, and cure the diseases that run rampant through this world, we would still have lots of money left over.
Humans may very well be the most evil, destructive, and monstrous race in all of existence.
