Rob Dunn, biologist and writer in the Department of Biology at North Carolina State University on popular science writing:

My writing opens up new perspectives I had been missing. It changes how I think about what matters. I feel an obligation to the public to help people understand the ecology and evolution of the world around us, and I think that this sense of obligation is an opportunity. On a more ordinary level, my writing allows me to engage more and different audiences.
