Jobs after doing biological sciencesWatch
The biggest one I have heard is becoming a teacher - which to me seems a little pointless as you merely become one link in a circle (just my opinion though!)
Obviously a phD would be useful and is a possibility for furthering my knowledge and buying more time to decide.
I'm not too sure about what lab work opportunities would open up, to be honest lab work seems a bit dull to me for a job day in day out.
Are there any other possibilities that you can think of? Marine biologist sounds nice of course, but jobs are few, far between and poorly paid - d'oh!
although if you are looking for a very well paid job then you can pretty much forget about research completely (unless you are a genius or can find an industrial company willing to pay a lot).
Research (moving up to management positions if you don't want to be stuck in the lab itself)
Yeah, marine biology is another one I guess; also conservation?
Academia - not necessarily teaching but maybe lecturing at a university (in addition to the research obviously)
I'd DEFINITELY go for the PhD if you want to work in science, especially research. You'll need to accept that scientists are not well-paid; unfortunately this seems to be a (hugely unjust) fact of life - unless you do something amazing or get really high up in the big pharmaceutical companies.
Alternatively, go in a completely different direction - maybe do a law conversion course and specialise in a related area of law (there must be one!), or go work in the City, or... well anything really. Employers seem to love scientists. You'd definitely make money that way...
