Thank you for your letter inquiring about the prospects of doing graduate work with me. The result is that biologists experience considerable difficulty finding gainful employment.
Jobs are in short supply with no relief in sight.
Being a plumber is a relatively safe profession, but ecological field work can be dangerous. Not many undergraduates should go on to graduate school. If you aren't absolutely certain that grad school is for you, then it isn't. Most of the best graduate students are those with an extraordinarily strong background in biology and with a real drive to study biological phenomena. To succeed in graduate school, you must be brave, driven and a workaholic, to boot.
