This form of waste disposal is an attempt for factory farms to be cost efficient. The environmental degradation resulting from pig farming presents an environmental injustice problem, since the communities do not receive any benefit from the operations, and instead, suffer negative externalities, such as pollution and health problems.

Multiple studies have found that increases in meat consumption are currently associated with human population growth and rising individual incomes or GDP, and therefore, the environmental impacts of meat production and consumption will increase unless current behaviours change.
On the other hand, a little over 50% of all pork production and 70% of all poultry production worldwide originated from animals kept entirely in confined buildings even around 2006, and the raw numbers were expected to increase by 3–3.5 times for pigs, by 2–2.4 times for layer hens and 4.4–5 times for broilers.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins.
Toxins may be introduced to meat as part of animal feed, as veterinary drug residues, or during processing and cooking. Such compounds are often metabolized in the body to form harmful by-products. Negative effects depend on the individual genome, diet, and history of the consumer. [81]
Feedback appears to have been originally researched in the 1950s. In the decades since, its usage in the pork industry has become widespread due to increases in the pork industry's size and increases in overcrowding. The change in the industry's size has led to a growing spread in diseases such as E. coli and PEDv. A lack of effective vaccines ...
