The Yangtze, an informal geography lesson

We spent a lot of time reading this book today, and it turned out being a lovely geography lesson as we learned about river sources, tributaries, erosion, rapids, dams, floods, farming, transport and pollution. It's amazing how much can be learned when it is put into context, I remember learning all these things at school but they had no context so often had to just be learned off by heart for exams.
