I've gone dumpster diving before, the amount of perfectly good food thrown is amazing, personally I only feel comfortable taking packaged goods though so I end up leaving a lot of it.
I wish this was true for the USA...they would rather throw it in a landfill than donate it to a pantry, or even homeless and if caught trying to take food from the dumpster they arrest you......
I've just come across this video here in October 2023. I've been dumpster diving for 12 months now. I've saved hundreds of dollars and never eaten so healthy.
