I knew I liked science a lot, but I didn't want to do labratory science or a specific area of science. I also liked to write a lot. A lot of people start with only bachelors degrees, though, and start as underwriters low down and work their way up.
Some people also do it through a degree in Journalism or English.
They have to learn more science, but as long as you like science and are willing to learn you can do it. A. Talking to scientists and being able to pass on the information in a vivid way. You have a lot of scientific adventures as a science writer. When you write, you never get to just do science writing. The stuff that isn't science writing isn't any fun, like going to meetings and things.
