<s>[INST] The next text is a question of a member of the European parliament:"Südwind and Global 2000 published a report entitled ‘Social destitution and overfishing to produce tinned tuna for European supermarkets’. Since 1950 the quantity of tuna caught has increased twelve-fold. According to FAO (Food and Agriculture Organisation of the United Nations) almost 5million tons of tuna were caught in 2012. Some of the nine types traded (such as Bluefin tuna) have already been decimated by overfishing. Inefficient catching methods also threaten other marine species as a by-catch. The fishing zones where there are not yet any problems are parts of the Pacific and the Indian Ocean. However, if the demand for tuna continues to rise as it has to date, these fishing zones too will soon be exhausted. Our seas are under enormous pressure from overfishing and pollution caused by our industrial production.  This gives rise to the following questions:      1.  What measures is the Commission taking in the battle against the overfishing of tuna?      2.  Forced labour and human trafficking are not uncommon on the floating fish factories. The EU has already taken some measures in this area, such as the ban on illegal and unregulated fishing in Thailand, but how specifically will this measure be monitored and controlled?"
