An appropriate and constructive programme of "social capital" was urgently needed to help citizens develop a concern for the environment, the Vice-President, Mr. Krishan Kant said. Inaugurating a conference on health and environment, organised by the Centre for Science and Environment, Mr. Kant said the basic issue underlying the problems of environment and health was that of technology choices. "Potential victims and the vulnerable sections in any disaster or pollution hazard, must have a say in the choice of technologies, processes and products" he said.
