It is my firm belief that factory farming is a root cause of most public health problems attributable to meat and eggs. e-coli outbreaks, salmonella, tainted watersheds - the list goes on and on. As consumers, we bear part of the responsibility. Where do you think the profit margin comes from on a $1 1/4lb hamburger? We need to consume responsibly, also cognizant of the fact that we in the developed nations over-consume carbohydrates, fats and proteins.
