Our Ammonia Map shows how much ammonia pollution chicken and pig factory farms are releasing into the air, and where.  Intensive indoor systems can create hotspot areas with very high levels of ammonia, and the health implications of ammonia are profound. Once that ammonia is released, it is blown across the country. That means the air you breathe can be impacted – even if you don’t live next to a factory farm. This is one of the many reasons we must stop the expansion of cruel factory farming.
