iBook: Withgott Environmental Science (aka "the frog book") 2012. We'll have copies of this on our class iPads, but if you want to get your own, you can share notes and other advantages-it is relatively cheap for the benefit it provides.
Other AP study guides you might want to invest in:

Barron's AP env science 2-15 6th edition (get the latest one)
5 steps to a 5-McGraw Hill 2018 (latest version has valuable updates)
AP env science crash course (2012) Older, but useful summaries
Another useful text: Withgott: Environmental science behind the stories 5th edition or 6th edition
This is the text we have used in the past. It is a college text, rather than an AP text like the one we are using. It is an excellent resource for diving deeper into topics, and gives great context for some issues we'll cover. Well worth the investment if you can get it.
