Global Impact

Marine biologists study sea life to better understand how the environment affects all living organisms. The common topics marine biologists study are astronomy, biological oceanography, cellular biology, ecology, chemistry, geology, zoology, and many others. The ocean covers 71% of the world. Because of marine biologists, 5% of the ocean has been discovered.
