The noted ecologist, Dr Vandana Shiva, today added one more dimesion to the talk of a "conspiracy" behind adulteration of mustard oil and expressed suspicions about the soyabean industry being the main beneficiary of the ban on mustard oil. Addressing a Press conference, Dr Shiva said the government decision to free imports of oilseeds, especially soyabeans, on one hand and banning the sale of mustard oil on the other, is not coincidental.
