TV is often disappointing, full of soaps, game shows and repeats but tonight we have a treat. 

Two documentaries deal with problems that every one of us will face and be impacted by. 

The first is by the excellent Horizon team and hosted be the venerable Sir David Attenborough  – How Many People Can Live on Planet Earth?  on Wednesday 9th december 2009 on BBC 2 at 9 pm.

I have mentioned before about the potential crisis that over population will bring to our planet but there are ways to tackle the problem if we recognise it and we act.  See the documentary and let me know your thoughts.

The Second is Hot Planet on BBC1 at 10:45 pm.  Presenter-scientists Iain Stewart and Kathy Sykes round up the best current wisdom on climate change and look at the implications.  This ties in well with the Copenhagen summit and should provide enough real evidence for all of the climate change deniers out there, although I don’t expect them to change their opinions.  Again, watch it and let me know your thoughts.
