Over 10.2 billion land animals are raised and killed within the meat industry in the United States every year. The industry's primary concern lies within the amount of profit made, leaving many detrimental actions and effects that take place insignificant, and unresolved. Changes within the factory farm meat production system need to be made because it is detrimental to the environment, includes horrific animal cruelty, and can be unhealthy for humans as consumers. What often goes unnoticed is the fact that the current factory farming industry in the United States has a severe impact on the environment and contributes to much of the rising pollution of today. The manner in which humans raise these animals and dispose of their waste results in at least thirty three percent of human caused gas emissions, which ultimately increase global warming. "Methane has 23 times the global warming effect of carbon dioxide, and two-thirds of all methane emissions worldwide come from industrial farming, largely from huge waste lakes (manure lagoons) that are often as big as several baseball fields.  (Quinn) In addition to this pollution of the air, the meat industry also wastes a large amount of the freshwater provided in the United States, as well as polluting a vast portion of it as well. On average, seventeen trillion gallons of water are needed each year to produce food for America's overpopulated livestock. Also, water quality suffers huge damages from this mass farming "According to the Environmental Protection Agency, agriculture is responsible for 70 percent of all water quality problems in the United States.  (Quinn) One example of this is a group of chicken farms along the shore of Maryland that produce, annually, over three billion pounds of raw waste, which in a larger scale, pollutes more than 173,000 miles of rivers and streams. With this industry continuing to grow at a rapid pace, what will become of our environment in a short ten years? Pollution is just about irreversible, and the way the meat industry currently produces its products is nowhere near efficiency.
