There are many dangers associated with factory farming. Because animals are kept in close confinement they are often mistreated, unhealthy, and standaradized for efficiency using hormones and genetic manipulations. Antibiotics are so heavily fed to factory farm animals that because humans have been eating them, we have increasing become resistant to antibiotics and so have the viruses that they are supposed to defend us from! The problem with agribusiness is it uses a lot of toxic chemicals in fertilizers and pesticides to grow crops and that gets into our food and hurts our health. It also gets into our water and hurts the environment, which in turn hurts us. So overall, factory farming is bad for humans and the environment.
For one thing, the healthy and necessary rotation of crops to replace nutrients in the soil is not a concern for factory farmers. They use the maure and chemical fertilizers which becomes very unhealthy for the soil, making it unusable for future. The manure contains antibiotics and growth hormones and heavy metals (Zn, Cu, Cr, As, Cd, Pb), which can get into the water supply and erode the soil further.
Manure from factory farms is of unimaginable proportions, which causes the most methane emissions in the US. May I remind you that methane is one of greenhouse gases, trapping 20 times more heat than carbon dioxide.
Factory farms use a huge amount of water and crops for feeding (mainly corn and soybeans). To keep up with this demand, growers of these crops use extensive techniques involving synthetic and chemical fertilizers that can be very damaging to the environment.
I have not even included the environmental impact of the machines used on factory farms.
In summary, factory farms cause degradation in soil, water pollution, air pollution and consume so much water and grain, that they push other farms to use chemical and synthetic practices, which carries with it the same problems.
FOOD FOR THOUGHT: Factory farming contributes to world hunger. How? Well, we feed the cows so much grain, and get very little meat back in comparison. The amount of grain that we feed one cow might feed 100 people but the cow might only feed 10, if that.
