Summary:

- The article discusses the issue of air pollution from industrial animal farming operations, particularly in North Carolina. It highlights how these facilities, known as "factory farms," release significant amounts of pollutants like ammonia, hydrogen sulfide, and particulate matter into the surrounding air.

- Researchers have used satellite imagery and air monitoring data to map the extent of this pollution, which can have serious health impacts on nearby communities. The article notes that the pollution disproportionately affects low-income and minority populations living near these facilities.

- The article also explores potential solutions, such as stricter regulations, improved manure management practices, and the transition to more sustainable, smaller-scale farming methods. It emphasizes the need for policymakers and the public to address this overlooked environmental justice issue.
