Why Factory Farmed Meat Causes So Much Pollution
Posted in Uncategorized on 09/30/2009 01:37 pm by FriendsOfCMost North Americans are now familiar with the term “factory-farmed meat.” Though somewhat rhetorical in its use, it is an accurate way to describe the process that has become “conventional” ranching and animal husbandry. There are, of course, many concerns from a humane treatment standpoint, but the pollution concerns from such operations are equally, if not more, compelling.
Consider what happens when you put several thousand cows together who are not part of the same herd. First and foremost, you get a lot of animal waste – enough to fill entire “lagoons” with the stuff. This is rarely, if ever, given much in the way of treatment before being put into the nearby environment. Such lagoons often overflow into river systems during storms, especially in states and provinces without regulation.
The practice of “finishing” these animals on grains allows them to fatten up before slaughter. It also changes their intestinal pH, allowing them to be susceptible to dangerous organisms such as E. coli and others. These grains are also far more likely to be contaminated with heavy metals and PCBs than pasture.
Pollution Accumulating in Your Dinner – Biomagnification Explained
When the landmark book Silent Spring was released in the 1960s, it was the first time the public was made aware of the dangers of chemical bio-magnification. In this particular case it was birds of prey accumulating massive amounts of DDT in their bodies that resulted in their inability to reproduce because of soft egg shells.
Since then, this has been observed in nearly every higher order creature on Earth with one chemical or another. Human beings are not immune. The affinity that some of the most dangerous chemicals have for lipids causes them to accumulate in fatty tissues. Any creature that eats another can easily take these toxins into their own bodies where they are also stored in fat tissues, often causing drastically higher levels of body-toxins than are observed in simpler organisms that are lower on the food chain.
