I have always had trouble with the argument that transportation of food did not have a big impact, and looked into it for my book. Everyone quotes an Our World in Data post, which is based on research by Poore and Nemecek, who measured the distances trucks travelled and the carbon emissions from standard transport. They ignored refrigeration, which significantly reduces mileage since the truck powers the refrigeration, and ignored refrigerant loss, which is about 20% per year of serious greenhouse gases. They basically ignored the cold chain that makes bringing lettuce and strawberries from California possible, and totals about 4% of global emissions. And now we are getting more local food in the Northeast and Canada from vast natural gas fired greenhouses. In short, we have to eat local AND seasonal.

And don’t get me started about abundance!

Keep talking about it. Most people just want easy ways to feed their families. For instance, when I started reading your publication last year, I switched from ground beef to ground turkey in pasta and tacos, with no complaints from the family. Small step toward a little less impact👍
