Apart from the online notes, there is no “textbook” for this course. However, if there was a textbook, then “Environmental Issues” by McConnell and Abel would probably be it. It uses simple mathematical ideas (mostly those that we will discuss in parts I and II of our course) to study a variety of “Issues” (probably more than we will be able to mention). Among these are water supplies, turfgrass proliferation, food production and diet, and the sustainable campus. Many of these “Issues” would make great subjects for stand-alone posts in the Student Blog.
The full reference is Dan Abel and Robert McConnell, Environmental Issues: Looking Towards a Sustainable Future. 4th edition, Pearson, 2012.
