About the field of Marine Science: The general field of biology encompasses an extremely wide range of fields and specializations since all life can fall under this general category. Marine biology also covers a wide range of the issues biology covers, but only those related to the ocean. Because the ocean environment tends to be a particularly delicate one, extensive study of marine biology is important for meeting the challenges of pollution and other issues threatening to destroy ocean life. Related fields include: cellular/molecular biology , conservation biology , developmental biology , ecology , evolutionary biology , microbiology/immunology , neurobiology , oral biology , structural biology , anatomy , biochemistry , bioengineering , bioethics , biomedical sciences , biometrics or biostatistics , chemistry , clinical laboratory sciences , genetics , oceanography , and wildlife sciences .
