New Career?

I've been thinking for a number of years about possibly pursuing a new career. I've had at least two already - my first career was as a big-firm corporate lawyer, ultimately focussed on the technology and financing world, followed by a second career in finance - institutional asset management with a speciality in private equity. I've been retired for almost a decade, and my youngest child just went to college, so the next career may await.

The area I'm interested in exploring is in the conservation/ecology field. The aspects that interest me are land preservation, conservation management, sustainable agriculture and the preservation of agricultural open space - a big issue in my part of the world - and urban ecology/sustainable development. There's a lot going on right now in all of those areas.

I may at some point want to pursue an advanced degree in one of these areas, but for now I have the idea of trying a series of volunteer stints/internships at several different organizations in the areas of my interest to see what they're like and how I might fit into such an organization. It should be interesting to see how this develops!
