Yes. Knowledge cannot be free. But this is undoubtedly the worse money-grabbing business model I have ever seen. Yes this is the latest edition, updated with the latest information and historical events. But to mark this book, paperback at 100 dollars and hardcover for 230 dollars, is absolutely terrible. The only thing changing with edition is connecting environmental policies with the most up-to-date stories. There is nothing else useful. Colleges and universities have worked with men similar to this guy to always steal money from student. Even those who are trying to work hard and earn a good degree. And especially from those who are from a lower income status. Absolutely deplorable. Go ahead and buy books from this guy if you want. But afterwards, burn it.
