A lot of manure is spread on land as fertilizer and much of it washes off the land and poisons streams, lakes and rivers. The effects on our physical health would be immediate. Cancer and heart attack, the nation's biggest killers, would drop. So would many other diseases now linked to consumption of animal proteins and fats, such as osteoporosis. We would cease ingesting the drugs pumped into meat and poultry.
Animals suffer for food fat.
Pigs are stacked in cages like cars in a parking ramp. They never go outside. They never exercise or relate to other animals until they are packed into trucks and taken to the slaughter house. Often in sub zero weather or sweltering heat. Terror is all they know on their trip to the slaughter house to become ham for the holiday, bacon and beef for the burgers, and fat for your arteries.
