Over 100 Nobel laureates have signed a letter to Greenpeace, asking the radical environmental group to end their campaign against genetically modified organisms. The letter’s signers include Nobel Prize winners in physics, medicine, chemistry and economics.

In a report from the Washington Post, signer Richard Roberts, winner of the 1993 Nobel Prize in medicine, criticizes Greenpeace for its “damaging” and “anti-science” practices noting that their misleading narratives are often just “a way for them to raise money for their cause.”

This isn’t the first time Greenpeace has come under fire for using scare tactics to round up monetary support. In fact, the forestry community is so fed up with Greenpeace’s practices that they filed a lawsuit against the group alleging racketeering. In the suit they call Greenpeace a “global fraud.”

Greenpeace’s stunts have gone from headline grabbing events, designed to draw attention to environmental causes, to efforts that are now accused of being part of a criminal enterprise. The group even trampled on delicate 1,500 year old monuments in the Peruvian desert in a stunt that the government called a “slap in the face at everything Peruvians consider sacred.”

A clear pattern is emerging when it comes to Greenpeace as it becomes a marginalized shell of its former self.

Greenpeace’s misguided attacks on canned tuna, that receive little if any attention because the campaign is such a blatant fundraising excuse based on few facts and a lot of plushy costumed hyperbole, has helped complete the group’s slide into embarrassing irrelevancy.
