Biologists study how living things work, how they interact with each other and how they evolve, according to the American Institute of Biological Sciences (AIBS). They study a variety of subjects, including evolution, natural history, and conservation of plants and animals. They have careers in medical research, health care, pharmaceuticals and education.
The AIBS explains that the work of biologists contributes to people's understanding about the natural world and helps address numerous issues, such as threats to human health, environmental degradation, and maintenance of viable and abundant food supplies. Research biologists use the latest scientific tools and techniques to study the natural world. They work in both laboratory settings and the natural environment to discover and learn how systems work. Biologists in the health care field develop public health campaigns to overcome diseases, such as tuberculosis, AIDS and cancer. They also aim to prevent the spread of rare, fatal illnesses.
Biologists in environmental management and conservation careers solve environmental issues, especially the conservation of the natural world for future generations, states the AIBS. In the education sector, life science educators encourage people to learn new things, and they work in classrooms, research labs or the natural field. Many biologists also combine their scientific training with other fields, such as biotechnology, forensic science, and politics and policy.
