The trace

How it reaches your house.

Starting from Crop seeds, we walked the supply graph hop by hop to the goods you buy and the companies you own. Each step is the engine’s reasoning, scored for confidence and cited where a source backs it.

1. First impact

   Frozen Vegetables (commodity) →supply up

   China

   China accounts for 68% of frozen-vegetable supply in the graph, so a large Chinese greenhouse expansion plausibly raises supply from that source.

   68% confidence

   Frozen Vegetables (commodity) →supply up

   Frozen foods

   Frozen vegetables are an input to frozen foods, so a larger supply of the input should increase frozen-food availability.

   61% confidence

   Pesticides and fungicides (fresh produce) →Stands to benefit
