I suppose everyone may be a bit tired of the way 'debates' tend to go on this forum...
Here is an episode from one of my favourite podcasts, The Life Scientific, introduced by Jim Al Kalilli, who is a physicist and broadcaster here in the U.K.
This episode deals with a fairly contentious issue Antartica. Have an open mind have a listen and say what you think.
It's an interview with Jane Francis who is Director of the British Antartic Survey.
