It was June of 1992. The location was Rio de Janeiro. The occasion was the world conference on environment and development. A large number of people had come out on the streets. They were protesting the arrival of George Bush senior, the then president of the US. Just before coming to the conference, Bush had visited a local shopping centre, urging people to buy more so that the increased consumption could rescue his country from financial crisis. Protesters were angered by his statement that “the American lifestyle is not negotiable”.
