Coming Back

A report that one third of 'extinct' Mammalian species are eventually (sometimes 100 years later) should not raise too many hopes (http://www.guardian.co.uk/environment/2010/sep/29/plant-species-face-extinction ). It is also predicted that 1 in 5 plants face extinction and that will accelerate the rate of animal extinctions. Talking of extinctions, I retire from University on 30th September. I will continue to exist in the Blogosphere!
