No, this is not a joke:
You just knew it was coming: At the request of the Swiss government, an ethics panel has weighed in on the "dignity" of plants and opined that the arbitrary killing of flora is morally wrong. This is no hoax. The concept of what could be called "plant rights" is being seriously debated.
A few years ago the Swiss added to their national constitution a provision requiring "account to be taken of the dignity of creation when handling animals, plants and other organisms." No one knew exactly what it meant, so they asked the Swiss Federal Ethics Committee on Non-Human Biotechnology to figure it out. The resulting report, "The Dignity of Living Beings with Regard to Plants," is enough to short circuit the brain.
A "clear majority" of the panel adopted what it called a "biocentric" moral view, meaning that "living organisms should be considered morally for their own sake because they are alive."
And you thought radical environmentalism had gone about as far as it could. It's OK to make fun of them, but these people are as serious as can be and have more supporters than we probably want to think about.
