Bisphenol A (BPA) is the basis for plastics such as polycarbonates and is found in consumer goods such as baby bottles, plastic microwave food containers and canned food and beverage linings. On October 2008, Canada became the first country to formally declare BPA hazardous to human health, due to its links with a wide range of health disorders from infertility, breast and prostate cancer, to thyroid malfunction, attention deficit syndrome and recurrent miscarriage. It is commonly found in PVC and PS plastic packaging (cordial bottles, yoghurt tubs) and in the lining of canned food tins.

Today, around 5 per cent of the world's entire fish catch, by weight, is tuna and the global tuna business is worth around $5.5bn. All of the 23 identified, commercially exploited stocks are heavily fished; at least nine of these are classified as fully fished and a further four classified as overexploited or depleted. Three stocks are classified as 'critically endangered', three as 'endangered', and three as 'vulnerable to extinction'. The magnificent and iconic southern bluefin tuna has been reduced by some 95 per cent of stocks before 1950.
