On Saturday, cities around the world held the Third International March Against Monsanto. In New York, hundreds gathered in Union Square for speeches and a performance by Reverend Billy and his HoneyBees, then marched downtown to Foley Square. The marches were held to protest Monsanto’s promulgation of GMO’s (genetically modified organisms) in the food supply. Protesters want Congress to label or ban outright the “Frankenstein foods.” While most genetically modified crops have been engineered to resist insecticides and increase yields, critics maintain they can cause health problems and harm the environment. As for Billy’s HoneyBees, it’s believed that a loss of biodiversity — due, in part, to pesticides from Monsanto and others — is harming bee health worldwide. Meanwhile, Harvard scientists are currently working to create allegedly superior titanium “robobees” to replace the earth’s natural pollinators.
