I graduated from one of the first multi-disciplinary environmental science courses
in the world and the first in the UK, from the then Plymouth Polytechnic 1973-76, 2.1 Honours CNAA now Open University, then spent two years researching at the U. of Bath in relation to 'environmentalism' in the areas of sociology and philosophy of science and of knowledge and the associated economics and politics (before finding my finance withdrawn for radicalism, meeting a French woman on the ferry leaving Ireland one evening and dropping out for a couple of years, then becoming an analyst programmer in London with an MSc from Essex); so although I've never been employed in that field I've been following, and thinking, and preaching to deaf ears for a long time.
Now I watch my back and help to build local community and make music: http://aridisland.com/records 
Glad to see you too putting your thinking-cap on, cilla4progress, thank you.
