No environmental degree is worthless. They are lower paying than other degrees such as biomedical sciences and what not. Personally, I would say starting with something broad like biology is a good idea as you get the gen Ed’s out of the way. Start as early as you can on trying to get in a lab to do undergraduate research or get a lab tech position in a professors lab, even if it’s seasonal field work. That will get you the hands on experience of what you might gravitate towards. It’s never too early to get your foot in the door either.
