This text is currently on its 16th edition, so why would you ever read the 3rd edition??? Perspective.
I am a professor, and I teach a wide selection of courses within the Env Sci discipline. What I have done is pull chapters here and there from this text, and incorporate them as discussion points into my current material. I do not tell the students that the book is older than them at first, and for the most part, they are genuinely shocked.
I also find that while many people will refer to Env Sci concepts as “common sense”, they do not appear to be things that people think about regularly. Further, it is the interconnected aspects that my learners struggle with the most. It’s common sense that things are connected, but how? They can’t comprehend the feedback loops. This text expounds on some of those aspects.
I have also found the government operation and land use planning components to be very useful for learners these days.
