A new regulation has 
gone into effect in the United States that requires livestock operations
 to report estimated emissions of ammonia and hydrogen sulfide to state 
and local authorities. This Environmental Protection Agency ruling 
resulted in part from the harmful effects to human health noted from 
these gases, which are emitted as a byproduct of certain livestock 
raising situations.
US Environmental Protection Agency, we are 
grateful for this measure to safeguard public health. Our prayers that 
all people soon turn to the 
meat-free diet for a safer and cleaner environment for all.
During
 the Climate Change International Conference on July 26, 2008 in 
California, USA Supreme Master Ching Hai spoke via videoconference about
 the dangerous health risks of gases emitted by the animal farming 
industry.
Supreme Master Ching Hai:
 Just the hydrogen sulfide alone can cause irritation of different body 
organs: eyes, nose, throat, bronchial constriction, spontaneous 
abortion, impaired bodily functions, headaches, dizziness, vomiting, 
coughing, difficult breathing, eye damage, shock, coma, and death, etc. 
If concentrated dose is high enough like, for example, 1,000 parts per 
million, ppm, then even one single inhalation, cause immediately 
breathing stop and collapse. 
So there were some reports about 
animal farms in Minnesota which produce also hydrogen sulfide that 
causes people in the vicinity to vomit so much that they had to flee 
their own homes. And another incident in North Carolina, in which 
residents from 26 counties are forced to stay indoor as the air quality 
so was poor and filled with pollutant, including highly toxic gas, 
hydrogen sulfide, from animals. I’m sure these are not the single 
incidents concerning hydrogen sulfide produced by livestock raising.
