Next stop: Warangal, the heart of one of India's huge cotton growing areas, where every shop there seems to sell chemical pesticides. It transpires that there is no fair trade there, so the farmers earn a very low price for their crops. In order to try to grow more cotton, they use lots of chemical pesticides but they do not take precautions like covering their faces or their bodies. This can have severe health consequences, particularly when they spray in the hot sun. As local fair trade campaigner B A Hepsibah explains to the teenagers. "They develop nausea, sickness and some, they'll have nervous problems."
