The Evolution of Refrigeration and Its Impact
Refrigeration has revolutionized food preservation and distribution, drastically transforming dietary habits and accessibility. Historically, the challenges of transporting perishable goods led to innovative cold chain solutions, such as the first transcontinental shipment of broccoli. Achievements in refrigeration technology paved the way for meat transport over vast distances, lowering prices and increasing consumption, particularly of red meat. However, as access to refrigeration expanded, it has contributed to increased food waste in developed countries, where consumers often overstock their refrigerators.
