Whats going on?

Hey, this poem just came to me, its not the best but it has some meaning.

The summers are colder
The nights are darker
The world is changing
Its not getting looked after

Men are killing each other
Raping and stealing from each other
Young children in Africa
Are living to suffer

There are wars over oil
Terrorist threats every day
Children too scared
To go outside to play

Everything has changed
Life just isn't the same
Money, Power, Greed
Its all to blame
