Blackberries aside, the article shares the stories of several invasivores who are committed to slowing species invasion by eating such delicacies as Canadian geese, lion fish, starlings, wild mustard, deer, Bermuda grass, thistles and the like (YUM). Which actually leads me to a funny story: My friend's parents belong to a CSA in the Bay Area and one day they received a large bunch of spindly greens tagged as Agretti with the suggestion of making agretti spaghetti. When they googled agretti, they found out that their CSA had given them a close cousin to tumbleweed, which was most likely not something they were actually growing on their farm, but rather a weed. As it turned out, agretti spaghetti was quite delicious so give invasivorism a try... It may sound a little ridiculous, but trying to eat invasive species is a very sustainable, probably pretty healthy (especially if you are running around hunting pigeons), and literal way to get back to the original land.
Also, here's the tag line: “Eat for the environment. Eat locally. Eat wild meat. Eat for habitat. Eat invasive.”
