Cambridge IGCSE™ and O Level Environmental Management Workbook (Cambridge International IGCSE)

I'm a Science / Geography teacher in Australia and bought it to supplement my teaching. So far, so good. It's a stand-alone resource: copy and go. Focuses on skills rather than content (graphing, interpreting, analysing, explaining etc). My only objection is that the perspectives of the authors are fairly industry biased (pro: G.M. foods, fracking, pesticides etc) which is an unforgivable sin only remedied by the careful use of white-out (liquid paper) on some of the pages.
