MALAWI SMOKE. Malawi has a long history of tobacco production, traceable back to the early 1920s. Over the past decade, Malawi has become one of the five largest tobacco producers in the world, largely due to low export tariffs, cheap labour and lack of regulations. According to the UN, more than 98 percent of this low-cost leaf is exported to the rich nations of the developed world – with most of it ultimately destined for the factories of three of the world's biggest and most profitable cigarette manufacturers, Philip Morris International, British American Tobacco and Japan Tobacco. Child labor in tobacco growing is dangerous and forbidden worldwide. Nevertheless, children work in all major tobacco growing countries in the fields. It is estimated that about 78,000 children in Malawi work on the fields. Children prepare seedbed, fertilize tobacco and spray pesticides.
