You need to start reading up on global trade

This BBC page is a good place to start - links to all sorts of information relevant to prior development, and what lies ahead

Here's a great collection of articles from the BBC on the hefty topic of Global Trade - it could easily form the basis of an independent reading and research task, with articles on the pros and cons of free trade, the impact of containerisation, trade wars, globalisation, and new trade links via train with China, amongst others - I reckon there's an example for every part of the Global topic. Given that careful reading of the AQA 25m essay "levels of response" table suggests that top band responses demonstrate "application to a given context" and "good use of data", and that evaluation is "well supported", the important of wider reading and knowledge of examples has never been greater.
