I was doing a library search for fish farming and this book came up. I am not usually interested in hot topics and whatever is heavily promoted by the media. I had to read this book because I became curious about the topic of the book. It is very interesting. I cannot say I agree with most of the opposing arguments in their arguments because mostly they are political and write their arguments to win a debate not to reach the best truth of the situation they can. That is why I have avoided following such debates because they prove to be giant wastes of time. I learned a lot from this book and plenty I already knew and realized I have about 50 more books in the opposing viewpoints that I will be reading. I speed read which requires pre-reading and so on but makes it possible to read a great deal in little time that becomes available. Opposing Viewpoints are written, in my reading, to be read very quickly which makes it a mandate to read the rest of them. I recommend reading it if you are interested in the topic.
