I realize that the course is long over, but I came across this article that I thought might interest some. Specifically, it addresses the heated topic discussed at lunch a few weeks ago. There are some skeptics out there who do not believe that deforestation is happening and that all is rosey. While the rate at which we are cutting trees is slowing, there is still a lot of work to be done to bring it to a sustainable level.

Sustainable Development & Competitive Advantage 
Good to see that Canada is listed as stable, but surprising that we actually had a debate at lunch about this.
