CAREERS RELATED TO BIOLOGY

1. Introduction

Biology, the study of living organisms and life processes, forms the foundation of many important careers worldwide. Every profession that deals with human life, animals, plants, microorganisms, or the environment is connected to Biology in some way. In Zambia and many other countries, Biology-related careers are essential because they contribute to health care, food security, environmental protection, industrial development, and scientific research.

As students study Biology from Form 1 onward, they build the basic knowledge, skills, and attitudes needed for future training in different biological fields. Understanding Biology careers helps learners appreciate why they study the subject, and how it connects to national development.
