On June 4th 10,000 Haitian peasants burned corn donated by Monsanto. Ana Jones at the Huffington Post has an article about it. They cite Farmer Leader Chavannes Jean-Baptiste of the Peasant Movement of Papay first hand. Right or wrong, here are his reasons why they chose to do this.

• Hybrid seeds are a poison gift. They don't reproduce,
  and therefore cannot be shared among a community. Haiti does not yet
  view seeds as a commodity like the US does. These hybrid seeds threaten
  the cultural fabric in Haiti because they break the cycle of food
  sharing.
• Jean-Baptiste believes that Monsanto has taken
  the opportunity of the recent earthquake in Haiti to intentionally
  introduce the seeds and destroy Haitian agriculture, creating a
  dependency on Monsanto each season for new seeds.
• If the
  Haitian government accepts Monsanto's seeds, rather than trying to
  build a system of food sovereignty, the Haitian farmer will become a
  day laborer, working for industrial farms. This would completely
  transform the economy to an industrial system instead of working to
  support farmers through a local economic system.
