Factory farms are increasing their production of meat to meet a growing demand that they themselves have created. This increase is met without any care for the land or the animals, or the small farms they claim to protect. They utilize fossil fuels to help maintain their machinery and take over the small farms that cannot hope to compete with large corporations.
Furthermore, these corporations focus simply on the need to make a profit, ignoring all those who depend on meat, sourced through factory farming, for sustenance.
Regardless of the size of the farm, be it large or small, the amount of resources are going to be the same, because animals eat the same quantity whether in tiny cages or out in the field. The shelf-life and geographical distance of the product and the farms respectively have to be taken into consideration. If the shelf-life of the meat is two weeks, but it takes three weeks to reach the market, the product is, in any case, considered a waste. Reducing the load on depleting resources is a facade fed to the public by large corporations who gain nothing but profit.
