This book is intended partly for the general reader who is interested in current affairs. It would also be useful for students studying politics, whether for GCSE, A-level politics or as part of their degree. David Spurling and David Westby, have tried to use their own experience, both within this country and elsewhere, to make the subject interesting, but also to show the wide variety of views on many political topics. In particular, it looks at environmental issues, which many natural scientists as well as social scientists regard as very important. This was in spite of the fact that in the general election 2017 in the United Kingdom that it did not register very highly as a topic.
