Lyrics of Mankind's not kind

Chickens abused in factories
Eggs produced for vital needs?
Cow are injected to get fat
The poor animals, they just go mad.
Oh yeah, our mankind's not so kind
Maybe it's the meat which made'em go wild
The results of all the anomals tests
Are of no use for the human quest
To live healthy and never die
They just don't hear the animals cry.
