The Monsanto Tribunal, a group of activists highlighting abuses by U.S. seed company  Monsanto (MON) today delivered an advisory opinion alleging the company "engaged in practices which have negatively impacted" people's rights to a healthy environment, food and good health, the AP reports. 

Monsanto has affected the livelihoods and health of farmers and others around the world with its sales of genetically modified seeds and the weed-killer Roundup, the Tribunal said.  

In response, St. Louis-based Monsanto says hearings last year that led to the ruling were staged by "a select group of anti-agriculture technology and anti-Monsanto critics who played organizers, judge and jury."
