whereas just "food desert" is currently considered (more from public health perspective) as places where the local populations do not have (convenient) access to affordable, healthy food, this more wholistic concept is a less human-centric understanding that implies both, a low, non-proportionate amount of food grown, and dependency on (usually both environmentally unsustainable and imbalanced fossil fuel energies and farm land stewardship) less-/unnatural imports of food from "non-renewable" or less lively (e.g. degraded/depleted top soils and watersheds) source farms
After being affected by the spirit of "deep ecology", I had a fresher awareness of the ironic, or at least unnatural, situation of how the grocery stores, markets, restaurants, etc. made it appear like there's an abundance of food, but our less- or unhealthy human-built environment that had me dependent on unsustainable, imbalanced energies (like fossil fuels and their corresponding implements) actually was an ecological food desert.
