Animal Agriculture and Pollution of Air, Water and Land

Animals are raised in concentrated animal feeding operations (CAFOs) known as factory farms.

Hundreds to millions of animals, usually dairy cows, pigs and chickens, are packed into massive windowless buildings where they are confined in boxes or stalls.

These factory farms produce huge amounts of animal sewage and other pollutants.

The quantity of urine and feces from the smallest factory farm is equivalent to the urine and feces produced by 16,000 humans.

The waste contains disease-causing pathogens, chemicals, pharmaceuticals and heavy metals.

Over 168 gases are emitted from the waste, including hazardous chemicals such as ammonia, hydrogen sulfide and methane.

Airborne particulate matter carries disease-causing bacteria, fungus or other pathogens.

Animals frequently die in factory farms, and their broken, lifeless bodies contribute to the waste.

Difference between Plants and Animals

ALL ANIMALS FEEL PAIN, but…

Do plants feel pain?  NO!  Plants do not have brains or central nervous systems.  They cannot feel anything.

In addition, since nonhuman beings generally possess keener, more acute senses than human beings,

nonhuman beings may feel more than human beings

according to Renowned Bioethics Professor Peter Singer who wrote Animal Liberation in 1975. 

All animals feel pain.  Professor Singer states, “The behavioral signs include writhing, facial contortions, moaning, yelping or other forms of calling, attempts to avoid the source of pain, appearance of fear and terror at the prospect of its repetition, screaming, crying, trying to physically escape.”(1)

Professor Singer explains that if sentient human beings feel pain, then sentient nonhuman beings do also because both species possess nervous systems.  Both sentient human and sentient nonhuman beings have “nervous systems which provide physiological signs of pain:  an initial rise in blood pressure, dilated pupils, perspiration and increased pulse rate, and if the stimulus continues, a fall in blood pressure.”(2)

Infamous and beloved Dr. Jane Goodall noted in her study of chimpanzees in In the Shadow of Man “when it comes to expression of feelings and emotions, language is less important than nonlinguistic modes of communication such as cheering, a pat on the back, an exuberant embrace, a clasp of hands, etc.  The basic signals we use to convey pain, fear, anger, love, joy, surprise, sexual arousal and many other emotional states are not specific to our own species.”(3)

SCIENTIFIC EVIDENCE SHOWS THAT CENTRAL NERVOUS SYSTEMS ENABLE ALL ANIMALS TO POSSESS THE ABILITY TO FEEL.

ALL ANIMALS HAVE CENTRAL NERVOUS SYSTEMS.

THUS, ALL ANIMALS HAVE THE ABILITY TO FEEL.

OKAY, NOW THAT WE UNDERSTAND NONHUMAN BEINGS DO, IN FACT, HAVE FEELINGS, WE KNOW THAT NONHUMAN BEINGS ARE SENTIENT because

Sentience is the capability of feeling.

Sentience represents the exclusive requirement for consciousness or self-awareness.  All human and nonhuman living beings possess sentience because all living beings have the ability to experience feelings of pain, sadness, loneliness, depression, pleasure, happiness, love, joy, etc.
