A biologist is a scientist who studies living organisms. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms function. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes. Some biologists work in management positions coordinating or supervising research.
Conservation biologists are concerned with the protection and sustainability of natural resources like air, water, land and wildlife. The job requires at least a bachelor's degree in a scientific field like biology, though graduate-level programs are often required, especially if teaching and research is a career goal. Many conservation biologists work with the government or private agencies, serving as consultants on land use issues.
