In 1970, Modified Atmosphere Packaging (MAP) technology emerged, altering the gas composition inside packaging to slow spoilage in fresh and preserved produce. This innovation significantly extended the shelf life of food products, impacting the food industry and consumer habits. MAP has become a standard practice in food preservation, enhancing food safety and reducing waste.

The emergence of Modified Atmosphere Packaging (MAP) in 1970 enabled global supply chains, which contemporary poetry began to address. Poets explored themes of globalization, consumerism, and environmental impacts, reflecting on the interconnectedness of modern life.
