Why Is Marine Biology Important?

Marine biology is important because by studying and researching ocean and marine environments, marine biologists play a key role in understanding climate change and identifying sustainable and profitable ways humans can use the sea and its resources. Marine biology involves the study of organisms, including viruses, bacteria, plants and animals, living in marine habitats. Marine biologists understand the needs of organisms in these habitats, ultimately helping protect species and reduce human threats.

Marine biologists quantify plant and animal life in marine habitats and keep close track of the overall health of marine ecosystems. As experts in understanding marine habitats, marine biologists often form essential parts of disaster relief teams. They respond to oil spills and chemical leaks, helping other scientists restore normalcy to local habitats. Sometimes marine biologists influence other spheres, such as economics and law. They might analyze the effects of sonar on whales and seals, for instance, recommending best practices for reducing harm on those sensitive populations. Marine biologists understand how oceans support basic needs, and in turn relay that information to lawmakers, who establish protocols regarding human use of ocean waters and marine organisms. Marine biologists help develop ocean technology too, improving waste elimination, energy sourcing and extraction of key resources.
