Germany is home to 83 million people. But that isn't the country's total population: It's also home to about 27 million pigs, 12.6 million cattle, and nearly 40 million egg-producing hens. Their lives are very hard. Many of these animals live their lives densely crammed together in industrial-scale agri-production facilities, under conditions that cause chronic distress to the animals - and would likely cause distress to many a meat- and egg-eater if they knew more about how factory-farmed food animals live out their lives.
The economics of meat, milk and egg production provide incentives for factory farms to grow to enormous sizes, with as many animals packed into as small a space as possible. In addition to causing endless distress to the animals, factory farms also produce a great stink, and they're a source of mountains of excrement that can pollute nearby waters, depending on how they're disposed of.
