Michael Palin sent this message to students on a new online university course:
"Geography is the subject of the moment..... As the most basic concerns about our continued existence on the planet are being raised at the highest level, the relevance of geography becomes more important than ever. Geography asks the questions we need to answer. The more you know about Geography the more you know about the future.”
If you want to know more about why you should study geography, there is this book available.
Over half of the initial print run of the book has sold, so you need to get a copy before too long, or perhaps more than one if you want to supply students in your groups with one, or have several copies for a departmental library, or school library.
