Impact on Farmers

• Because of their close contact, farm workers are especially vulnerable to health effects of herbicide, with the EPA conservatively reporting 10,000 to 20,000 related incidents each year.
  
  

Wildlife Impact

• A 1992 study published in the journal, BioScience, reported over 67 million birds die each year from pesticide exposure on U.S. Farms.
  
  

Long-Term Effects

• Long-term health effects of many herbicides are not known, which is complicated by the fact that many herbicides such as aminopyralid persist in the environment.
  
  

Widespread Effects

• Health effects can become widespread by nonpoint source pollution (NSP) when rain or precipitation wash herbicides into waterways, including drinking water.
