In general it was very good. The "looking at the facts without taking sides" -approach is good for discussing things objectively and the author succeeded in that quite well.
Few times he seemed to jump to a conclusion, which was not entirely supported by the presented data. But this is not a research paper and it discusses so many topics that all the data cannot be included. I would need to read the related references to understand better the conclusions.
One thing is very clear, Canadians (and many other rich nations) are not doing their share when it comes to protecting the environment.
