In Finland, there is an ancient law called the jokamiehenoikeus (translated literally to mean “every man’s right”). It permits anyone to walk, ski, or cycle in the wilderness including private property provided that one acts responsibly. You can even camp for the night on another person’s property as long as you are not too close to anyone’s home. Also, anyone is allowed to forage for berries and mushrooms from the forests and wilderness. Mushroom picking is especially popular.
I guess that dumpster diving could be considered another form of gleaning, but I’m not sure that’s legal here. This past Sunday, while waiting for a bus, I saw someone dumpster dive in broad daylight. This dumpster is next to a grocery store called Alepa, which evidently provides some prime pickings. I’m assuming the perpetrator found some goodies because she was in there for five or so minutes and she left with a full bag.
