The art of war

When the bright stars start to fade away
And the nature begins to die
You know these are the signs
Signs that tell us the truth
That the human kind as taken it to far
That the boundaries have been broken
The same boundaries that unite us to everyone and every thing
This action...is war!
The most cruel event that as started so many years ago
But why?
Why does the human kind start these wars?
Is it really because of "terrorism" or "well being for others" ?
Maybe it's because the human kind doesn't know how to listen
Listen to all the real problems this world faces
Hunger, poverty...murder!
These...these are the problems the people is this universe should fight against
To try make this world better
Yet I know...
I know that they don't care
I know that it's going to be hundreds of years before the human kind realises it
I know that these changes are never going to happen
And it makes me sad
So I ask...
Is it possible for one person to change the world?
