Bottles of Monsanto's Roundup are seen for sale June 19, 2018 at a retail store in Glendale, California. A former groundskeeper who contracted terminal cancer after years of working with Roundup, a popular herbicide which Monsanto claims to be safe, is suing the chemical giant over allegations that exposure to the active ingredient in Roundup, a chemical called glyphosate, caused his non-Hodgkin lymphoma (NHL). San Francisco Superior Court Judge Suzanne Ramos Bolanos has been assigned to the trial which is tentatively expected to begin on June 21. / AFP PHOTO / Robyn Beck
