effects of factory farming on the environment

What do you think of when you envision farm animals? Do you think of a fat cow in a sun-drenched pasture munching on some green grass? Or do you imagine some chickens lazing about pecking on the ground for seed outside of a beautiful red barn? These scenes look wonderful on a post card but are not the actual proceedings at farm factories. The truth is that in the brutal farm factories' never ending search of ways to lower costs and thereby increase profits, they have resorted to feeding these poor abused creatures that which is unbelievably unhealthy for them and also for the humans that consume their flesh.
