The documentary The Power of Community: How Cuba Survived Peak Oil demonstrates how Cuba experienced "artificially imposed peak oil" after the fall of the Soviet Union in the 1990s when it lost most of its food and oil imports. Cuba responded by transitioning to an organic agricultural system of locally produced food, with a high degree of community support and interaction.
Our current system of travelling food is highly dependent on nonrenewable resources which we are depleting at an ever increasing rate. There are concerns about food security as we approach peak oil. In this context, the discussion about local food will likely eventually become one of necessity. Many have suggested that Cuba is an excellent model for avoiding food shortages.
