I’ve worked in engineering firms for the past 10 years and I’ve found that entry level Environmental Science folks don’t always have degrees in that field or even BS degrees at all. I knew one with a degree in Economics, another who had simply spent several years doing asbestos remediation work as a contractor. Many of the major firms doing NEPA or state environmental law documentation hire cheap labor that can learn on the job. Like someone mentioned before, it doesn’t pay as well, but it is a job. I’d say let the LA degree demonstrate your ability to think and start making calls. However, you might do some research into your state’s environmental laws and NEPA before picking up the phone.
