My most influential teacher taught Geography. He was very good at explaining the subject, but he was also very humane. He would put information in context, and talk about how the world was changing. I think he talked about the population explosion. How people were being exploited, and how countries were growing cash crops despite their populations needed food for themselves. So as well as learning about oxbow lakes and contours on maps we learnt a lot about the world. I don’t think we would have been taught like that today.
