Final answer:
Companies like Smithfield are problematic in the food industry due to consolidation and monopolization, profit-driven practices, and a dependency on global food chains.
Step-by-step explanation:
Companies like Smithfield are problematic in the food industry for several reasons. Firstly, they contribute to the consolidation and monopolization of food production. This leads to a lack of competition and control in the industry, allowing these companies to influence regulatory controls on food safety and dictate prices.
Secondly, these companies prioritize profit over ethical and sustainable practices, leading to environmental degradation, the mistreatment of animals, and the use of additives and medications in food products. Lastly, their practices create a dependency on global food chains, making the food supply more vulnerable to disruptions and scarcity.
