Introduction
The livestock production industry has experienced a significant transformation within the past few decades. Production systems have shifted from small, family-owned farms to larger farms that may only raise a single species. While this industry shift has allowed us to become more efficient, it has also threatened the health of the environment.
Environmental health is the art and science of the protection of health, promotion of aesthetic values, prevention of disease and injury through enhancement of environmental hazards and reduction of hazards. Important environmental considerations of livestock production include mature and waste management, water and air pollution, and threats to human workers. This paper will discuss these topics, as well as introduce relevant laws, regulations, and possible alternatives that exist.

Overview of Livestock Production Systems
Livestock production systems in modern day America are based on an industrial model, where animals are housed together in feedlots or climate-controlled buildings. These systems are referred to as confined animal feeding operations, or CAFOs. The size of each CAFO may range from less than one hundred animals to hundreds of thousands of animals. Types of CAFOs include hog barns, cattle feedlots, industrial dairies, and poultry operations
Due to the large population of animals housed within a CAFO, there is much concern about the impact of these operations on the environment as well as public health.
