The truth is no one really knows how much factory farm waste is escaping into our environment because no federal agency collects consistent and reliable information on the number, size, and location of large-scale agricultural operations, nor the pollution they’re emitting. Without this information, no one can monitor and hold CAFOS accountable for mismanaged waste and related health and environmental damage. Stanford Law Professor Daniel Ho and PhD student Cassandra Handan-Nader are hoping to change that.
