Not that I want to start sounding like an ad for the BBC, but I’d just like to flag up the fact that the final episode of Planet Earth Three airs on BBC1 tonight. I find it staggering that Sir David Attenborough is still making such wonderful programs: over the last few episodes, the great man has, once again, shown us the beauty and majesty of the natural world. Last week I found it captivating to see how humans are effecting nature and how animals are starting to adapt to human-built environments. Attenborough has opened our eyes to nature like no-one else, over a career without parallel. I find what he has achieved utterly mind-blowing, and while I’m certainly looking forward to watching tonight’s episode, I really hope we haven’t seen the last of Sir David Attenborough, the greatest broadcaster ever.
