The broccoli jungle
When I visited the supermarket as a kid, and chanced upon the broccoli section, I would imagine the stacks of broccoli as the canopy of a thick, impenetrable rainforest, similar to the untouched parts of the Amazon. And when shoppers took the broccoli, I imagined deforestation taking place. That made me sad.
The comparison between broccoli and pristine jungle remains with me to this day.
