I have always had a love for animals (especially reptiles, I have 5 snakes) and animal science. Especially conservation. But I have also discovered that I have a love for physics and engineering. How many years of schooling are we talking here if I major in somekind of animal science (say, zoology) and/or physics and engineering? What kind of jobs could I get with these degrees? Maybe even a PhD? I'm a sophmore in highschool right now. Thanks.
