Niraj Agarwal, independent candidate from South Kolkata for the Lok Sabha election, is focussing his campaign on environment issues. He goes about with a group of five supporters, spreading the message of making a change with saving the environment. "We chose the binocular as our election symbol. It help us to look at things which are at a distance. The issues that we are fighting for - environment, sustainability, waste management - need a lot of foresight," said Niraj Agarwal.
