Why have Indian farmers been protesting for months?

On February 21 about 120,000 Indian farmers gathered at a grain market in Punjab to protest against the government. The crowds of men and women arrived early, making their way to the market in tractors, buses, trailers and cars. They waved flags and vowed to head south to the capital of New Delhi to make their voices heard.  Waiting for them in Delhi were tens of thousands more farmers who had been camping near the highways leading into the capital for months.   On this week's Beyond the Headlines, host Taylor Heyman looks at why India’s farmers have been moved to launch these protests.
