Transport is a small contributor to emissions. For most food products, it accounts for less than 10%, and it’s much smaller for the largest GHG emitters. In beef from beef herds, it’s 0.5%.
Very little food is air-freighted; it accounts for only 0.16% of food miles.
Many of the foods people assume to come by air are actually transported by boat – avocados and almonds are prime examples. Shipping one kilogram of avocados from Mexico to the United Kingdom would generate ... only around 8% of avocados’ total footprint. Even when shipped at great distances, its emissions are much less than locally-produced animal products.
Are you the average meat eater then? I assume most folks on HN are talking in generalities that can be applied to large populations.
The heavily-processed vegetable-based "product" aggressively marketed to you has been shipped halfway round the world, having been farmed using just about the least sustainable farming practices imaginable.
