Yeah, that hit me a while back. In my experience, I started just looking at where my food comes from. For example, I'll pick apples from a local farm stand instead of bagged ones from far away. Also, cutting down on meat, especially beef, made a big difference based on what I've read. Your mileage may vary, but these small swaps added up for me over time.

Convincing the crew was the easiest step in the whole process. Everyone already wanted in on the idea before I even finished explaining it. That first bin only brought in pocket change, less than the cost of the coffee we drank while planning.
