Animal farms
produce massive
amounts of animal
waste like urine and
manure that emit
around 400
different harmful
gases into the
atmosphere (nitrous
oxide, ammonia,
particulate matter,
endotoxins, and
hydrogen sulfide)
AIR POLLUTION
Most of the
methane comes
from cows on
factory farms that
are fed low-quality
grains that their
bodies were not
made to digest,
resulting in high
levels of digestion
and flatulence. All
of this gas then
enters our
atmosphere
