Air. 1  The massive amounts of excrement produced by livestock farms emit toxic gases such as hydrogen sulfide and ammonia into the air. Roughly 80% of ammonia emissions in the U.S. come from animal waste (The U.S. Environmental Protection Agency).

Direct emissions come from fertilized agricultural soils and livestock manure (42%). While indirect emissions come from runoff and leaching of fertilizers (25%).
