What do you find most and least interesting about environmental studies?

As a classically educated biologist, the most interesting aspect of environmental studies is how living systems manage to survive and even thrive in new and changing conditions. But I find that I am learning so much about so many different topics, that I can honestly say that each day is a learning experience.

I sometimes grow frustrated that I cannot deal with more progress in teaching or in my consulting work. One example is the local issue of the Chesapeake Bay. The governments around the Chesapeake Bay, where I live, signed the first Chesapeake Bay Agreement in 1985, nearly 30 years ago and the largest problem remains. The difficulty in solving the problem is not lack of knowledge on how we can solve the problem, but the difficulty in generating the will to solve the problems.

Are there subfields of environmental studies that students might not be aware of?

That is hard to say, because any subject area students can think of has an environmental field -- all the sciences (geology, hydrology, biology, chemistry, psychology, anthropology), engineering, economics, sociology, art, literature, and education.

What careers do students commonly pursue with a degree in environmental studies?

For the longest time, environmental studies graduates went into some area of science, management, or law with a company, university, or government. But that pattern has changed incredibly in the past 10 years or so, and I see the job opportunities continuing to expand. I see jobs and careers in the environmental field that did not exist 10 years ago. Perhaps the field that is expanding the most is restoration of streams, rivers, fields, and forests.

Is a graduate degree preferable for a career in environmental studies, or can someone enter the field with a bachelor's degree?

Some people find that an undergraduate degree suits their job and career interests, and in others, a graduate degree is necessary, so it depends. The sciences are more likely to expect a graduate degree, especially if there is research in the job.

Do you think environmental studies is a subject that can be studied online, or is a traditional class environment ideal?

I have taught several online courses, and if done properly, online courses work fine. I think the important aspect of environmental studies courses is a strong emphasis on practical aspects, not just theory.
