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.
