The three careers I'm thinking of joining is Marine Biology, Submersible Vehicle Design and Oceanography. The reason why I want a career in Marine Biology is because I want to know what makes human and mammals in the ocean different. I want to know te different kind of species there is in the ocean and what kind of organs do the mammals have in the body. I want to learn Submersible Vehicle Design is because I want to know how they design the vehicles they need for the expedition and I get to design vehicle by the way I imagine. Also, is because I can fix the vehicle faster and I will know what tools I might need to finish the vehicles without underestimating myself. Lastly, the reason why I want a career in Oceanography is because I will want to learn the different ways of a oceanographer works and how they work as well. I will like to know the materials and procedures of how to finish a work or project.
