Posible Junior Theme Topic?

So today in the library, I found it really helpful to look on the class links website to search for and choose a possible JT topic. One of my favorite topics was the Environmental/ Wildlife conservation topic. I Soon discovered that even in that topic, there are hundreds of ways Icould branch off and write my paper. Im having trouble thinking about how to address my problem. When I talked to Bolos, he gave me the idea that branching off into more of a political aspect, and talking about how presidents in the past, and present have delt with conservation issues. I think that would really give me a solid idea to write about and there is a lot of information on the internet. My only problem is finding a novel that addresses that topic. Any suggestions?
