World cotton prices have dropped to a historic low: the reason being the immoral continuation of EU and US trade subsidies that allow non-competitive and inefficient farming to continue. Cotton subsidies in richer countries cause over production, artificially distorting world markets. Yet it is the poor countries, whose economies are wholly dependent on the cotton trade, who suffer. In Burkina Faso, one of the world's poorest countries with few other natural resources, cotton is the country's main cash crop. It is their primary source of foreign income, and the lifeblood for the majority of farmers - 2 million people depend on cotton for survival.
