Turf grass. It’s the stupidest crop ever cultivated by humanity.
Lawns are an 17th century European fashion trend. We poison the soil with herbicides to defend grass. We poison the water with fertilizers to feed grass. Many US households through HOAs or zoning regulations are legally required to cultivate and martian grass. Grass doesn’t feed anyone, except the insects that die soon afterwards from all the poison.
Watching Youtube videos. It’s as good as college for anyone with a little savvy. I’ll bet that Youtube employs more PHD philosophers than any three universities.
