Final answer:
The pork industry has undergone significant changes from the past to today, with a shift from small farms to large-scale factory farming operations. Technology has also played a role in improving efficiency and productivity in the pork industry.
Step-by-step explanation:
The pork industry has undergone significant changes from the past to today. In the past, pork production was mainly done on small farms, where pigs were often fed table scraps and lived in small enclosures. Today, the pork industry is characterized by large-scale factory farming operations, where pigs are raised in confinement and fed formulated diets.
One key difference between the past and today is the scale of production. In the past, pork production was much smaller in scale, with pigs being raised on family farms. Today, the pork industry is highly industrialized, with large-scale operations producing pork on a massive scale.
Another difference is the use of technology. In the past, farmers relied on traditional methods of pig farming, while today, the industry has adopted advanced technologies to improve efficiency and productivity. For example, modern pig farms use automated feeding and climate control systems to optimize pig growth and health.
