Intensive animal farming

Intensive animal farming or industrial livestock production, also known by its opponents as factory farming,[1] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production, while minimizing costs.[2] To achieve this, agribusinesses keep livestock such as cattle, poultry, and fish at high stocking densities, at large scale, and using modern machinery, biotechnology, and global trade.[3][4][5][6][7] The main products of this industry are meat, milk and eggs for human consumption.[8] There are issues regarding whether intensive animal farming is sustainable[9] or ethical.[10]

There is a continuing debate over the benefits, risks and ethics of intensive animal farming. The issues include the efficiency of food production; animal welfare; health risks and the environmental impact (e.g. agricultural pollution and climate change).[11][12][13]
