bigcatguy: I'm wondering what your major was in college, and also any advice on how to make such a huge impact on animal conservation as you have.
Peter Gros: I would recommend zoology and a minor in environmental science. Most zoos would be very helpful in guiding you towards conservation projects that may interest you — try contacting their education departments. You may also want to join or start a speaker's club, which will give you a venue to share your information and affect groups of people with your conservation ideas once your research is completed. Good luck with this! It's certainly a very rewarding career path.
