Environmental impact of animal production Environmental impact of animal production One of the biggest topics of animal agriculture shown through the media focuses on the impacts animal production has on the environment. Each and every human has made an impact on the environment and the world in which we live, so it is no surprise this is the same case with animals. Below are some common questions asked pertaining to the environmental impacts of the animal agriculture industry, and answers to those questions. Do animals make greenhouse gases?

Commercial shrimp farming began in the s, and production grew steeply, particularly to match the market demands of the USA, Japan and Western Europe. The total global production of farmed shrimp reached more than 1.
The largest exporting nation is Thailand. Shrimp farming has moved from China to Southeast Asia into a meat packing industry.
Technological advances have led to growing shrimp at ever higher densities, and broodstock is shipped worldwide. Virtually all farmed shrimp are penaeids i.
These industrial monocultures are very susceptible to diseases, which have caused several regional wipe-outs of farm shrimp populations. Increasing ecological problems, repeated disease outbreaks, and pressure and criticism from both NGOs and consumer countries led to changes in the industry in the late s and generally stronger regulation by governments.
Animal law In various jurisdictions, intensive animal production of some kinds is subject to regulation for environmental protection. In the United States, a Concentrated Animal Feeding Operation CAFO that discharges or proposes to discharge waste requires a permit and implementation of a plan for management of manure nutrients, contaminants, wastewater, etc.
Inthe US Environmental Protection Agency published 5-year and 1-year data on environmental performance of 32 industries, with data for the livestock industry being derived mostly from inspections of CAFOs.
Of the 32 industries, livestock production was among the top seven for environmental performance over the 5-year period, and was one of the top two in the final year of that period, where good environmental performance is indicated by a low ratio of enforcement orders to inspections.
Also in the final year, the livestock industry was one of the two leaders among the 32 industries in terms of having the lowest percentage of facilities with violations. In Canada, intensive animal production, like other agricultural sectors, is also subject to various other federal and provincial requirements.
In the United States, farmed animals are excluded by half of all state animal cruelty laws including the federal Animal Welfare Act. The hour law, enacted in and amended in states that when animals are being transported for slaughter, the vehicle must stop every 28 hours and the animals must be let out for exercise, food, and water.
The United States Department of Agriculture claims that the law does not apply to birds. Originally passed inthe Act requires that livestock be stunned into unconsciousness prior to slaughter.
This Act also excludes birds, who make up more than 90 percent of the animals slaughtered for food, as well as rabbits and fish. Individual states all have their own animal cruelty statutes; however many states have a provision to exempt standard agricultural practices. In Ohio animal welfare organizations reached a negotiated settlement with farm organizations while in California, Proposition 2, Standards for Confining Farm Animalsan initiated law was approved by voters in In order for this to happen, several actions need to be taken and these four components include: There are differences around the world as to which practices are accepted and there continue to be changes in regulations with animal welfare being a strong driver for increased regulation.
For example, the EU is bringing in further regulation to set maximum stocking densities for meat chickens by[ needs update ] where the UK Animal Welfare Minister commented, "The welfare of meat chickens is a major concern to people throughout the European Union.
This agreement sends a strong message to the rest of the world that we care about animal welfare. Animals are often under stress from being kept in confined spaces and will attack each other.
In an effort to prevent injury leading to infection, their beaks, tails and teeth are removed. Factory farms are a popular way to gain space, with animals such as chickens being kept in spaces smaller than an A4 page.
The largest pork producer in the U. Human health impact[ edit ] According to the U. Centers for Disease Control and Prevention CDCfarms on which animals are intensively reared can cause adverse health reactions in farm workers. Workers may develop acute and chronic lung disease, musculoskeletal injuries, and may catch infections that transmit from animals to human beings such as tuberculosis.
One source of this is bioaccumulation in animals raised on factory farms. Residents near such farms report problems such as unpleasant smell, flies and adverse health effects.
Antibiotic use in livestock may create antibiotic-resistant pathogens; parasites, bacteria, and viruses may be spread; ammonianitrogenand phosphorus can reduce oxygen in surface waters and contaminate drinking water; pesticides and hormones may cause hormone-related changes in fish; animal feed and feathers may stunt the growth of desirable plants in surface waters and provide nutrients to disease-causing micro-organisms; trace elements such as arsenic and copperwhich are harmful to human health, may contaminate surface waters.
Many communicable animal diseases spread rapidly through densely spaced populations of animals and crowding makes genetic reassortment more likely.
However, small family farms are more likely to introduce bird diseases and more frequent association with people into the mix, as happened in the flu pandemic  In the European Uniongrowth hormones are banned on the basis that there is no way of determining a safe level. The UK has stated that in the event of the EU raising the ban at some future date, to comply with a precautionary approach, it would only consider the introduction of specific hormones, proven on a case by case basis.
Furthermore, in the European Union banned all drugs for livestock that were used for growth promotion purposes.
As a result of these bans, the levels of antibiotic resistance in animal products and within the human population showed a decrease.Environmental and animal welfare groups sent a letter to Oregon officials, asking them to shut down a controversial mega-dairy.

and Their Impact on Communities. Author. Carrie Hribar, MA Project Coordinator – Education and Training. We advocate for the animals by helping to pass legislation to protect animals from abuse and neglect.
We also work to ensure effective enforcement of our current animal protection laws. Understanding Concentrated Animal Feeding Operations. and Their Impact on Communities. Author. Carrie Hribar, MA Project Coordinator – Education and Training. Animal farms may produce food, but they also produce massive amounts of animal waste like urine and manure that emit around different harmful gases into the atmosphere.
