I know that if you pursue it as a public interest career (I suspect most jobs in environmental law are public interest) then it will be very competitive. Public interest jobs are relativly rare, and to get one you should really try and go to a school with a good program, in a big public interest city. Another thing to consider is how to deal with your debt, since these types of jobs don't pay very well. Certain schools have phenomenal LRAP (loan repayment assistance program) which will lessen or eliminate your debt after several years of work in a pub interest job. Definilty check out the environmental law program, LRAP, and the schools rate of placement in envronmental law jobs. Good luck!
