Research: Research biologists study the natural world, using the latest scientific tools and techniques in both laboratory settings and the outdoors, to understand how living systems work.
Health care: Biologists develop public health campaigns to defeat illness and prevent the spread of deadly diseases. Veterinarians tend sick and injured animals, and physicians, dentists, nurses, and other health care professionals maintain the general health and well being of their patients.
Environmental management and conservation: Biologists work to solve environmental problems and preserve the natural world for future generations. Park rangers protect state and national parks and educate the public. Zoo biologists carry out endangered species recovery programs. Management and conservation biologists work with communities to develop management plans.
Education: Life science educators help people to learn new things in classrooms, research labs, the field, or in museums.
New directions for biological careers in the 21st century:
Biotechnology: Biologists apply scientific principles to develop and enhance products, tools, and technological advances in fields such as agriculture, food science, and medicine.
Forensic science: Forensic biologists work with law enforcement agencies using scientific methods to discover and process evidence to solve crimes.
Politics and policy: Science advisors work with lawmakers to create new legislation on topics such as biomedical research and environmental protection.
Business and industry: Biologists work with drug and science product companies in testing, sales, marketing, and public relations.
Economics: Biologists work with the government and other organizations to address the economic impacts of biological issues, such as species extinctions, forest protection, and pollution.
Mathematics: Bioinformatic and computational biologists apply mathematics to solve biological problems, such as modeling ecosystem processes and gene sequencing.
Science writing and communication: Journalists with science backgrounds inform the public about emerging biological issues.
Art: Life sciences illustrations in textbooks and newspaper/magazine articles are created by artists with an understanding of biology.
