169-171. I write about the destruction of the Selar Farm Site of Special Scientific Interest to make way for an open cast coal mine. This extract from a Parliamentary debate at the time conveys some sense of the discussion then going on about the adequacy of laws to protect key wildlife habitats. http://hansard.millbanksystems.com/lords/1996/mar/27/selar-farm-sssis

170-171. The Nant Helen mine has continued to stimulate environmental activism. Whereas in the 1990s this was in large part due to wildlife impacts more recently it has been because of climate change. http://www.indymedia.org.uk/en/2010/08/457201 More on the mine can be gleaned from the website of Celtic Energy http://www.coal.com/operations/operations-nant-helen-extension/

171. On the league table of which countries have contributed most carbon emissions on a per person basis since 1850 see this excellent summary published by The Guardian: http://www.theguardian.com/environment/2011/apr/21/countries-responsible-climate-change
