Botany is the study of plants. That sounds simple, but when you consider that plants include plankton, algae, and fungi, you soon realize that botany's field is the entire earth! Careers in this field include ecologist, conservationist, taxonomist, horticulturist, agronomist, plant geneticist, and many others. Botany is tackling some of the world's most pressing problems: How to reduce air and water pollution, how to feed an exploding human population, how to conserve energy, and so on. So it's a field blossoming with opportunities for curious minds.
