I have always thought that if modern technology were used to make something nutritious out of various weeds, we'd all be better off. Giant thistles. Ragweed. Dandelions (yes, I know the French and others eat the greens, but they eat snails, too). Burdock. If there is a more useless plant in the world than burdock, I'd like to hear it. All that vegetable energy used to produce a burr that winds itself into any kind of fur so tightly that it's easier to cut or burn it out than to try to extract it. Take that perversion and use it to make a nutritious seed! Cockleburs, all the other "I'm going to lodge in your hair/fur and go for a ride" plants. Pigweed. I mean, pick one. All you guys going for a PhD in biology, find a weed and find a way to make it a food crop. You don't even have to change the plant, just find a way to process it into something edible or useful. PLEASE!
