Air Quality: Intensive pig farming operations can generate odors, dust, and air pollutants such as ammonia and hydrogen sulfide, which can impact air quality and human health, particularly in nearby communities. Proper ventilation systems, odor control measures, and setback distances can help mitigate air quality issues.
Antibiotic Resistance: The use of antibiotics in pig farming to promote growth and prevent disease can contribute to the development of antibiotic-resistant bacteria, posing risks to both animal and human health. Antibiotic stewardship practices and alternative disease prevention strategies are important for addressing this issue.
Biodiversity Loss: Habitat conversion for pig farming and associated agricultural activities can lead to loss of biodiversity and fragmentation of natural habitats, affecting wildlife populations and ecological processes.
