Lars Eighner wrote an essay On Dumpster Diving.
It may be summer break from school for some, but this really is worth a read. Here are some highlights:
“I like the frankness of the word scavenging, which I can hardly think of without picturing a big black snail on an aquarium wall. I live from the refuse of others. I am a scavenger. I think it a sound and honorable niche, although if I could I would naturally prefer to live the comfortable consumer life, perhaps – and only perhaps – as a slightly less wasteful consumer, owing to what I have learned as a scavenger”
“The land is now covered with cities. The cities are full of Dumpsters. If a member of the canine race is ever able to know what it is doing, then Lizbeth [their dog] knows that when we go around to the Dumpsters, we are hunting. I think of scavenging as a modern form of self-reliance”
They go into detail about the different types of food and other items they find and the safety of consuming them, but with a philosophical streak.
This hopefully will be a book you won’t want to trash!
