Marine biology is a multi-disciplined area that incorporates various topics such as astronomy, cellular biology, molecular biology, physical oceanography, zoology, geology, genetics, food science, meteorology, chemistry, ecology and biological oceanography. Why is marine biology very important for us to explore? Because our life and the health of the planet rely on the ocean and it highly affects climate change, pollution, air quality and the like. Moreover, there are many species in the ocean endangered because of human interruptions. So, we have to protect them as we do with many many endangered species on land.
