No legal advice, but I am pretty sure picking an apple from a tree in a public space (but can be privately owned) for direct consumption is legal in Germany. Weird but understandable that you need a law for that.
ironically i think this is technically not covered by nordic “right to roam” as that says you should avoid areas near housing, however if anyone tries to raise a stink about people picking fruits from public trees then everyone is going to tell them to shut up and stop being a miserable idiot.
Laws regarding public access to nature are much better in Europe & the UK than in the US.
If I remember correctly, Trespassing isn’t a viable law in Finland.
You want to walk across the land? Go ahead.
In the US: CRIME
But what if you want to make moonshine or cook meth? How are you supposed to get some privacy with people traipsing all over the place?
Not just crime but in large parts of the country it’s a popular myth that they can shoot you for being on their property. They can’t, that’s ridiculous, but Hollywood and popular myth won’t let it die.
