Earth & Sky 2010
Earth & Sky was a free, public access course staged by the Ecospheres Project in 2010.
It looked at our home planet in its astronomical setting, discussed the basis of planetary habitability and focussed in on ecological issues at various scales from the global to the parochial, with discussions of initiatives to promote biodiversity in wild life corridors in southeast London, U.K..
It received a uniformly positive response from all participants.
