Activists wearing brinjal-shaped masks marched into the Erragadda Rythu Bazar on Tuesday morning to raise awareness among vendors and consumers on Bt Brinjal, a genetically-modified strain created by agriculture company Monsanto. The campaign, organised jointly by the Greenpeace and the GM (genetic modification) - Free Coalition of India, sought to boost awareness on Bt Brinjal before a consultation on the modified plant to be held in the city on January 22.
