On tonight's Horizon on BBC 2 Sir David Attenborough will be presenting a programme on the human population issue. I haven't seen a preview, but it is potentially one of the most important TV programmes of 2009. Sir David speaking out on the issue, at a time when carbon and climate change are high on the agenda, is very significant. It can be argued that addressing the human population issue is as important, if not more important than addressing carbon emissions. That is simply because rising human populations are the root of all the pollution, climate change, forest destruction etc. So please watch it and let us know your views tomorrow.
