What classes should I take for marine biology?

<p>Hey CC people. I'm going into the 9th grade next year and I was wondering what classes I should take if i plan on being a marine biology major. I know that I need to take as many classes as I can that focus on science, math, and writing. Anything else? My main goal is to have a carreer in an environmental advocacy organization. I know a degree isn't really nessecary to have that kind of carreer, but i want to get one anyway. I've been researching a lot of stuff trying to find out what all I have to do, so I have a general idea of things. Just checking to see if I missed anything :) thanks</p>
