The dairy industry involves the production and processing of milk and milk-based products. It includes activities such as farming, where animals like cows, goats, and sheep are raised for their milk. The milk is then processed into various products, including cheese, yogurt, and butter, which are consumed worldwide. This industry plays a significant role in the economy, providing jobs and contributing to food supply. Dairy farms vary in size, from small family-run operations to large commercial enterprises. The industry also faces challenges, such as animal welfare concerns and environmental impacts related to greenhouse gas emissions.
